9 Best 12 Oz Tumbler | 12 Ounces That Hold Ice Past Lunch

Specs are compiled from manufacturer listings and verified buyer reviews and can change over time — please confirm the key details on the product page before buying.

A quick note on sizes: not every pick below is the exact size or number you searched — where the exact one is scarce, the nearest same-type option that serves the same purpose is included so you get real, in-stock choices. Each pick’s actual specs are listed.

A 12 oz tumbler is the just-right size of drinkware — big enough for a real pour of wine or a full cup of coffee, small enough to actually fit in your hand and your car’s cup holder. The trick is that “12 oz” shows up in a lot of different bodies: squat stemless wine cups, tall coffee tumblers, kid-friendly sippy cups, and multi-packs built for a whole household. This guide sorts nine genuinely good ones so you can match the cup to how you actually drink, not to a spec sheet.

I’m Mo Min — the founder and writer behind Non Toxic Blog. This guide is built by comparing the manufacturers’ published specifications and the patterns across verified customer reviews, so you get each pick’s real strengths and trade-offs instead of marketing spin.

You want a 12 oz tumbler that keeps your drink cold and your hand dry. This list uses flexible matching, so a pick may offer 12 oz as a selectable size rather than being the exact ounce count you typed in — the nearest same-type size serves the same job. From budget basics to premium ceramic-lined cups, here is the honest rundown of the best 12 oz tumbler.

How To Choose The Best 12 Oz Tumbler

A 12 oz cup sounds like a simple purchase, but the size label hides three totally different products: a wine-style stemless cup, a coffee travel tumbler, and a kid’s sippy cup. They all hold roughly the same amount, yet they fit your hand, your bag, and your morning routine in ways that have nothing in common. Nail down how you’ll use it first, then let the specs do the rest.

Interior Material Changes How It Tastes

Stainless steel is the standard build — durable and neutral, but some people pick up a faint metallic note in coffee or tea. A ceramic coating lines the inside of the cup so the flavor stays clean. That matters most for black coffee, green tea, and anything where you’d notice a tinny edge.

Insulation and Condensation

Double-wall construction means there are two layers of material with a gap between them, so the outside of the cup never sweats and leaves a water ring on your table. Vacuum-sealed versions take that further and hold temperature for longer. If you’ve ever wiped a puddle off a wooden desk, this single feature is the fix.

Lid Design and Leak Risk

A lid is only as good as its seal. A threaded or screw-on lid with a silicone gasket holds up best for travel, while a slide or flip top is convenient but can seep over time. If the cup is going in a bag, prioritize a lid the maker actually calls leak-proof rather than spill-resistant.

Cup-Holder and Hand Fit

Tumbler widths vary a lot, and a few millimeters is the difference between a cup that slots into your car’s holder and one that rolls around the passenger seat. If you drink on the move, check the base width before anything else.

In‑Depth Reviews

★ Best Overall

1. Tervis Clear & Colorful Tabletop 12oz Made in USA Double Walled Insulated Tumbler Travel Cup, 4-pack

Our pick — over 4.5★ from 20,000+ verified ratings; the strongest balance of quality and price.

Double-wall TritanMade in the USA

Four double-wall Tritan cups that stop condensation cold — the highest-rated pick here at 4.7 stars across 20,000+ owners.

Sitting at 4.7 stars across more than twenty thousand ratings, the Tervis earns the top spot on the strength of one job done flawlessly: killing condensation. Each cup is built from double-wall Tritan, a tough BPA-free plastic with two layers and an air gap between them, so a cold drink never wets the outside and never leaves a ring on your desk. The set is called “Clear & Colorful” for a reason — the tinted walls let you tell one person’s cup from another’s without a label.

What wins people over is sheer build quality, with temperature retention close behind — the insulated wall keeps ice rattling well past lunch. The cups are dishwasher safe, and owners in hot, humid climates say that’s the whole point: no sweaty, slick surface to grip, no puddle under the glass. The maker builds them in America and backs them with a Lifetime Guarantee, which is unusual at this price point for plastic drinkware.

The catch is weight and footprint. Each cup is a chunky object rather than a slim wine glass, and the four-pack is meant for a table or a cabinet shelf, not a single-person commute. There’s also a long-tail delivery gripe — a few buyers waited two-plus weeks for theirs to arrive. skip it if you want something to toss in a bag; grab it if your kitchen is where drinks actually get drunk. As buyers report, “Ice lasts long, no condensation, sturdy, nice-looking.”

Where it earns its keep

  • Double-wall Tritan construction stops condensation so no water rings form on your table
  • Impact-resistant and BPA-free, so a dropped cup doesn’t shatter
  • Dishwasher safe for easy cleanup after a party
  • Backed by the maker’s Lifetime Guarantee

Worth knowing before you buy

  • Bulky, wide footprint compared with a slim wine tumbler
  • Not designed for a single commuter’s bag
  • A few owners mention slow shipping

Your pick if: you want four durable, condensation-free cups for home and everyday use.

Look elsewhere if: you need a slim, lightweight cup to carry in a bag.

Best for Kids

2. Yummy Sam Stainless Steel Cups with Straws and Lids, 12oz Spill-proof Kids Tumblers, 5 Pack

304 Food-Grade Steel2-in-1 Lids

Five unbreakable 304 stainless steel 12 oz cups with silicone sleeves and two lid styles apiece.

Five short steel cups with non-slip silicone sleeves — the kind of set that ends the cycle of replacing cracked kid cups every few months. Each one is made of 304 food-grade stainless steel, the same family of steel used in kitchen cookware, and it’s unbreakable the way plastic and glass are not. Every cup ships with a lid, a straw, a sleeve, and a BPA-free build, so a nursery or a playroom is stocked in one go.

The 2-in-1 lid is the quiet genius here. You can sip through the straw with the lid on, or drink directly like a regular cup. Owners also like that the color-coded silicone sleeves stop collisions in a crowded playroom. The lips are silicone, so you get a cushion of grip even when little hands are wet.

Here’s the fair warning: the leak-proof seal is only as good as its setup. Get the ring seated correctly and say goodbye to leaks; skip that step and the same ring is where the drips come from. Some owners note that the silicone sleeve can trap water underneath. As customers note, “Great cups. Love for smoothies. The lid stays shut and doesn’t allow liquids to leak out.” Clean them properly and they repay you tenfold.

The kid-proof factor: five cups, ten lids, and five sleeves mean you can stock the whole cabinet without a single glass cup in the mix.

The honest catch: the seal relies on a correctly seated silicone ring, and a few reviewers point out that straws can be bitten through with heavy use — worth knowing if you’ve got a chewer.

Made for: households with toddlers who drink smoothies, milk, or juice daily.

Not the right fit if: you want a lid that seals without any assembly or cleaning care.

Wine Lover’s Choice

3. Corkcicle Stemless Wine Tumbler with Lid, 12 oz, Latte

Ceramic-Coated InteriorTriple Insulation

A ceramic-lined stemless wine tumbler that holds white wine cold for six hours with no metallic aftertaste.

Corkcicle solves a specific problem: the tinny, metallic flavor that stainless steel can leave in wine and tea. The fix is a ceramic coating on the inside wall, so your drink tastes like the drink, not the cup. The trade-off is size — at 3.43 inches wide and 4.45 inches tall, it’s a compact, palm-friendly shape compared to the Tervis at 8 inches wide and 5 inches tall, so a smaller hand can wrap around it comfortably. That’s a fit advantage over some stemless designs.

And it is heavy in the hand — at 7.04 ounces versus 12 ounces for the Tervis, it carries its weight in a way that feels premium rather than flimsy. The triple insulation gets 6 hours cold and 3 hours hot, a step up from what you’d get from a simple double-wall cup, which makes it a fit for slow sipping on a patio. Reviews frequently mention enjoying a genuinely cold pour even in a hot summer.

The honest catch: the outside ceramic finish doesn’t always survive a dishwasher. A few shoppers say the coating peeling after the first wash. If you love the look and want it to stay that way, hand-washing is the safest bet. Several owners also say the lid is splash-resistant rather than totally sealed. As one buyer put it: “This is the perfect cooler for wine. Easy to grasp for smaller hands.”

The flavor upgrade: the ceramic-coated interior keeps wine and tea tasting clean, with no metallic note — a real advantage for anyone who’s been put off by standard stainless.

The care trade-off: durability of the coating is the recurring gripe, so hand-wash if you want the finish to last.

Reach for this if: you drink white wine, tea, or coffee and hate the taste of metal.

Think twice if: you want a cup you can toss in the dishwasher without a second thought.

Best Giftable

4. Swig Life 12oz Insulated Wine Tumbler with Lid, Scrub Life

Triple Copper-PlatedBuilt-In Coaster Base

A print-forward 12 oz stemless wine tumbler that keeps white wine cold for nine hours and looks gift-wrapped even when it’s for you.

Swig Life leans into the parts of a tumbler people actually photograph: a glossy glossy print finish, a removable slider lid, and a nonslip silicone base molded right into the bottom. The triple insulation — stainless steel, wrapped in copper, then sealed — keeps cold drinks cold for nine hours and hot drinks hot for three. That nine-hour window is the standout number here, well beyond the three-hour hot rating on the same cup.

Wine fans get a balance in this size. It’s 3.25 inches wide by 4.5 inches tall, so it holds a generous pour without feeling like a bucket. The built-in coaster base stops the cup from sliding across a glass table. It’s top-rack dishwasher safe, and the removable slider lets you choose how freely you sip.

The two things to know: the base is only as permanent as it feels. A handful of buyers report the rubber base popping out, which is worth checking on arrival. And Swig recommends hand-washing the printed designs if you want them to stay bright. It’s also priced at the higher end for a single cup. This one is as much a gift as a piece of gear — the packaging-friendly prints make it an easy pick for a wine lover, a nurse, or a birthday.

Why it works for wine

  • Holds cold drinks cold for 9 hours — the longest cold window in this lineup
  • Built-in nonslip silicone coaster base protects tables and grips surfaces
  • Removable slider lid lets you control how freely you sip
  • Top-rack dishwasher safe

Keep in mind

  • Some owners mention the bottom rubber base loosening over time
  • Hand-washing preserves the printed design best
  • Premium price for a single cup

A strong buy for: gifting, casual entertaining, and anyone who wants their cup to look as good as it performs.

Maybe not if: you’re shopping for value across several cups rather than one statement piece.

Best Value Set

5. ATZNZIK 4 Pack Insulated Coffee Mug with Lid, 12oz Travel Coffee Tumbler, Multicolor

4-Pack, 4 ColorsDouble-Wall Vacuum

Four stainless coffee tumblers in four colors, built to hold six hours of heat and eight hours of cold apiece.

If you want one tumbler per household member, this is the value play — four insulated cups in black, red, blue, and green. Each one is a double-wall vacuum design, which means two steel layers with the air pumped out between them, so heat doesn’t leak through the wall. The manufacturer rates them at 6 hours hot and 8 hours cold, and the 12 oz size slots into a car cup holder.

The lids are the detail worth calling out. Each has an airtight silicone seal to stop spills and a small air vent so liquid flows out smoothly instead of glugging. The exterior is wrapped in a silicone texture for grip, and there’s a non-slip bottom to stop the cup sliding across a desk. The stainless body is described as rust-proof and reusable — a genuine upgrade over disposable cups.

The honest trade-off is temperature precision. One owner measured their coffee dropping to lukewarm within about an hour and a half, which is well short of the 6-hour claim. That’s the nature of a value-priced vacuum cup: it slows heat loss, but doesn’t eliminate it. A few owners also note that a lid can arrive with a missing rubber gasket. Buy it for value, color-coded household logistics, and easy cleanup — not for a lab-grade temperature hold.

Where the value shows: four insulated cups in four colors with airtight sealing lids — a genuinely economical route to a fully stocked kitchen cabinet.

The realistic caveat: coffee stays warm rather than steaming, and the lids are the weak link — check the gasket on arrival.

Best for: families, offices, and anyone who wants several tumblers rather than one.

pass on it if: you need a cup that keeps coffee piping hot for the whole workday.

Prettiest Pick

6. Corkcicle x Rifle Paper Co. 12 oz Insulated Tumbler, Garden Party

Rifle Paper Co. PrintTriple Insulated

A floral-print 12 oz stemless tumbler from the Corkcicle x Rifle Paper Co. collab, triple-insulated for six hours cold.

This is the highest-rated cup in the lineup at 4.8 stars, and the reason is in the name: Rifle Paper Co.’s Garden Party print. The surface is a proper artist-designed pattern rather than a plain color, and reviews keep coming back to how vivid the colors and how detailed the design are. Build quality backs it up — the weighted bottom is called out as something that keeps the cup from tipping over on a patio table.

Performance-wise, this is a triple-insulated stainless cup rated at 6 hours cold and 3 hours hot, so a full glass of wine stays chilled through a slow dinner. It’s BPA-free and top-rack dishwasher safe, and the slightly wider body does a good job of holding up to a real pour without spilling. Flat sides give a secure grip, so it sits comfortably in the hand — the sort of detail that makes it feel less like a gadget and more like a nice piece of serveware.

The honest catch is that some owners say it’s priced higher than plain stainless tumblers, and they accept that as the cost of the design. That’s a fair trade if you want the print; if you want plain efficiency, you’ll pay less elsewhere. Otherwise, the objections are minimal — the collab has held up well over time, and the finish doesn’t tend to chip the way some printed cups do.

The standout: the Rifle Paper Co. print is unusually refined for drinkware — it looks like a piece of art rather than a product label.

The honest note: you’re paying a design premium, and it’s overkill if you just want a workhorse cup to knock around.

Choose this one if: you want a wine tumbler that looks as good on the table as it functions.

Pass if: you need maximum value-per-cup rather than a decorative piece.

Best Flavor Control

7. Owala SmoothSip Slider Insulated Travel Coffee Cup 12 oz, Very Very Dark

Ceramic-Lined InteriorLeak-Proof Slider Lid

A ceramic-lined 12 oz coffee tumbler with a leak-proof slide-top spout and up to 24 hours of cold retention.

Owala’s SmoothSip is the most technically ambitious cup on this list, and the two specs that matter are the ceramic-coated interior and the completely leak-proof lid. The ceramic lining means coffee and tea taste clean, with none of the metallic edge a bare stainless cup can carry. The liner answers the same problem the Corkcicle cups solve, but targets coffee drinkers instead of wine sippers, and it does so in a taller, narrower body.

The insulation keeps drinks hot for hours and cold up to 24, which is the widest cold window in this entire lineup — nothing else here comes close to that 24-hour figure. The slide-top spout sits flush on the lid, so no splash escapes even when you’re moving. The lid itself is dishwasher-safe, while the cup body is hand-wash only, per the maker.

The one nagging trade-off: the interior coating is black, not the expected white, which some owners say makes it hard to spot stains at a glance. A few also wonder how the coating holds up to a metal spoon over the years, so use a wooden or plastic stirrer if you’re the careful type. The base has no rubber grip, so add a silicone sleeve if you set it down hard on stone countertops. For a serious coffee drinker who wants a leak-proof cup that tastes clean, it’s the strongest option on the page.

The two numbers that matter

  • Cold retention up to 24 hours — the longest cold rating in this lineup
  • Ceramic-lined interior keeps coffee and tea tasting clean, no metallic aftertaste
  • Completely leak-proof slide-top spout survives a backpack commute
  • Dishwasher-safe lid for simple daily cleanup

Small things to know

  • Hand-wash-only cup body
  • The interior ceramic coating is black, so stains are harder to see
  • No rubber grip on the base — add a silicone sleeve if you’re rough with it

Tailor-made for: coffee and tea drinkers who want clean flavor and a lid they can trust in a bag.

it’s not for you if: you insist on a fully dishwasher-safe cup or want a rubber-bottom base from the start.

Best for Long Shifts

8. MiiR Flip Traveler 12oz, Tidal Blue

100% Recycled SteelDouble-Wall Vacuum

A slim 12 oz recycled-steel travel tumbler with a locking flip lid, built to keep coffee hot through a nine-hour shift.

MiiR’s Flip Traveler is the “leave the house at 6 a.m. and don’t come back until dark” cup. The double-wall vacuum insulation keeps black coffee hot for six to eight hours, according to how owners use it on long shifts — a number that lines up with the smaller 2.76-inch-by-6.53-inch body, which is tall and slim enough to slide into a cup holder without wobbling. The design also earns praise for balancing a sleek matte look with practical non-slip texture.

The tall, narrow build is the key spec here. A slim body holds heat the way a wide, low tumbler can’t, because there’s less surface area for warmth to escape through. It’s also excellent for ice retention. It’s a genuine travel cup, with a flip lid that locks into place for low-maintenance commuting and a nonslip coating that keeps the cup steady on a car seat or a train tray.

The trade-off is care. This model isn’t dishwasher safe, and owners who ran it through anyway report the paint bubbling and peeling after a year of part-time use. The flip lid also doesn’t extend far back, which makes the last sip a little awkward unless you remove the cap. And about one in a handful of users find the lid tricky to remove fully for cleaning. Wash it by hand and it will match the ambitions of a commuter’s schedule.

The long-haul payoff: a slim recycled-steel build rated to hold coffee hot for 6 to 8 hours, which is what makes it the best match here for long shifts and travel days.

The catch: hand-wash only, or the paint finish can bubble and peel over time.

Reach for this if: you’re on the go for nine-plus hours and want one cup that lasts the whole shift.

Think twice if: you want dishwasher-safe convenience and a flip lid that folds fully clear.

Best for Customizing

9. Wzaytia 12 Oz Sublimation Sippy Cups Blank, 6 Pack, White

Sublimation Coated6-Pack, Gift Boxed

Six blank 12 oz stainless sippy cups with a sublimation coating for pressing your own design, each individually gift-boxed.

If the phrase “custom kids’ cups” is what brought you here, this six-pack is your answer. Each of the six cups wears a sublimation coating, a spray-on layer that lets a heat press transfer a printed design permanently into the surface. That means you can put a kid’s favorite cartoon, a name, or a party theme directly onto the cup instead of sticking on a label. The results, owners say, come out vibrant rather than washed out.

The body is 304 18/8 stainless steel with double-wall vacuum insulation, rated to keep drinks cold for 12 hours and hot for 5. Each cup arrives with two lid options — a handle lid for little hands and a straw lid — plus a straw, a rubber base, a gift box, and a shrink wrap, all individually packaged. The dual-lid setup means the same cup adapts as a child grows out of the sippy stage.

What you’re buying here is a blank canvas plus the accessories to finish the job, which is why it’s a strong pick for small businesses and baby-showers alike. A couple of practical notes: align your design with the handle before you press, and use heat tape to keep placement straight. Both are tricks owners share rather than flaws in the cup itself. look elsewhere if you just want a ready-to-drink cup from the start, since the whole point is the customization.

Why crafters keep buying it

  • Sublimation coating transfers designs vividly and permanently
  • Two lid styles per cup — a handle lid and a straw lid — extend the cup’s useful life
  • Cold for 12 hours, hot for 5, per the maker’s double-wall vacuum rating
  • Individually gift-boxed with straws, bases, and shrink wrap included

Before you press

  • Requires a heat press to apply your own design
  • Alignment with the handle takes care and heat tape
  • Not a ready-to-use cup straight from the start

Built for: crafters, small businesses, and anyone making custom cups for kids or baby showers.

Not for you if: you want a cup to drink from the moment it arrives.

Understanding the Specs

Double-Wall Insulation

Two layers of material with a gap in between — the gap is what stops heat from moving through the wall, so a cold drink stays cold and the outside stays dry. A vacuum-sealed version pulls the air out of that gap for even stronger performance. On a value cup, the effect is real but gradual; on a premium one, it’s closer to a full-day hold.

Vacuum Insulation

Vacuum sealing takes double-wall construction one step further by removing the air from the gap entirely, so there’s nothing left to carry heat across. It’s the reason a coffee tumbler can hold heat for hours while a plain double-wall cup cools in one. It adds cost, but it’s the single biggest driver of how long a drink stays at temperature.

Ceramic Coating

A thin ceramic layer applied to the inside wall of the cup. Stainless steel can leave a faint metallic note in coffee, tea, or wine, and the ceramic layer blocks that transfer so the flavor stays clean. It’s the reason a ceramic-lined cup tastes different from a bare steel one, and it also means careful cleaning matters more — hand-washing keeps the coating intact longer.

Capacity and Cup-Holder Fit

Capacity is measured in fluid ounces, and 12 oz is the common balance — a full pour of wine, or a coffee with room to spare. The width of the base decides whether the cup sits in a car holder or rolls around the seat. A wider, stouter body holds more comfortably on a table; a tall, narrow one travels better.

FAQ

How much liquid does a 12 oz tumbler actually hold?
Twelve fluid ounces, which is roughly the same as a standard wine pour plus a little room to move. That’s why so many stemless wine tumblers land on 12 oz — it’s enough for a generous glass without leaving the cup heavy in the hand. In coffee terms, it’s a full mug with space for cream, as one owner of the Owala SmoothSip noted for a 10 oz pour with 2 oz of cream.
Is a 12 oz tumbler the same as a 12 oz travel mug?
Not always. A tumbler usually has a wider, open top and a simple lid, while a travel mug leans taller and narrower for a cup holder and a tighter screw-on seal. Both can hold 12 oz, but a travel mug is built to be carried and a tumbler is built to sit. If you take coffee on a commute, look for a maker’s leak-proof lid claim rather than just the capacity.
Will a 12 oz tumbler fit a car cup holder?
It depends on the base width, not the ounce count. A cup around 3.25 to 3.5 inches wide, like the Swig Life or the ATZNZIK set, tends to slot into a standard holder, and both Yummy Sam and MiiR customers note theirs fitting car holders. A wide tabletop-style tumbler, by contrast, is meant for a table rather than a car.
Do I need a ceramic-coated or bare stainless steel tumbler?
Ceramic wins if flavor matters most. Coffee, tea, and wine can pick up a faint metallic taste from bare stainless steel, and a ceramic coating like the one on the Owala SmoothSip or the Corkcicle Stemless blocks that transfer. Bare stainless steel is tougher and simpler to clean, so it’s the better choice if durability matters more than taste.
Are these 12 oz tumblers dishwasher safe?
Mostly, but read the fine print on each cup. The Tervis set is dishwasher safe, and the Swig Life tumbler is top-rack dishwasher safe. The Owala SmoothSip splits the difference — the lid is dishwasher safe but the body is hand-wash only. The MiiR Flip Traveler is not dishwasher safe at all, and owners who ran it through report the paint peeling.
How long does a 12 oz tumbler keep drinks cold?
It ranges widely with insulation type. The Owala SmoothSip rates cold retention up to 24 hours and the Wzaytia sublimation cups rate 12 hours. The Swig Life tumbler holds cold drinks cold for 9 hours, and both Corkcicle cups rate 6 hours cold and 3 hours hot. A simple double-wall cup like the Tervis keeps ice rattling well past lunch without a printed hour rating.
Is a 12 oz tumbler good for kids?
It can be, if you pick the right build. The Yummy Sam set is unbreakable 304 stainless steel with a 2-in-1 lid and a straw, plus a non-slip silicone sleeve. The Wzaytia sublimation cups are also kid-oriented and ship with a handle lid and a straw lid. A glass or thin-walled adult tumbler is the wrong call for little hands.
How do I stop my 12 oz tumbler lid from leaking?
Check the seal before you blame the cup. Airtight lids rely on a seated silicone gasket, and if the ring is misaligned or missing, drips follow. The ATZNZIK set and the Corkcicle Stemless both use a silicone seal, and a few owners note that the lid is splash-resistant rather than fully sealed on the Stemless. Threaded and screw-on lids like the MiiR Flip Traveler tend to seal tightest.
Can I put hot coffee in any 12 oz tumbler?
Hot drinks are fine in an insulated stainless cup, but watch two things. First, cups with a printed or coated finish usually shouldn’t be microwaved, and second, the lid must handle heat without warping. The ATZNZIK mugs rate 6 hours hot, the Wzaytia cups rate 5 hours hot, and the Corkcicle and Owala cups rate 3 hours hot — so the cup, not the drink, sets the limit.
What is a sublimation sippy cup and who is it for?
A sublimation cup is a blank stainless sippy cup with a special coating that accepts a heat-transferred printed design. You press your own image into the surface, and it stays put. The Wzaytia 6-pack is the example here — 304 18/8 stainless steel, double-wall vacuum insulated, with a handle lid and a straw lid per cup. It suits crafters, small sellers, and anyone making personalized gifts.

Final Thoughts: The Verdict

For most people, the strongest 12 oz tumbler is the Tervis Clear & Colorful 4-pack, because four condensation-free cups cover a whole household and the Lifetime Guarantee is hard to argue with. If flavor purity is the priority, the Owala SmoothSip Slider wins on its ceramic lining and up-to-24-hour cold rating, while the Corkcicle Stemless is the one to reach for when the drink is wine and the setting is a patio. One gentle nudge: the Tervis holds the top score at 4.7 stars, and its review base is deep enough to trust that number.
