THERMOS ALTA SERIES Stainless Steel Tumbler, 12 Ounce, Slate

UPDATE: After using this cup every day for one year, it’s still in great condition. It has held up nicely in the dishwasher and the lid comes apart so easily for extra cleaning. The snap sipper cover has not worn and locks in place securely, providing a tight seal. Still ⭐️⭐️⭐️⭐️⭐️. After buying many thermal cups and returning them because they didn’t stay hot long enough for me to finish drinking my coffee in about a half-hour, I’ve finally found the perfect thermal cup. The difference is the vacuum seal. Well made and sturdy; tight seal and does not leak; stays very hot for about an hour and warm for a few hours; fits nicely under my small Keurig without having to remove the bottom piece; dishwasher safe; easy to remove the sturdy lid; easy open and close sipping hole. This cup is not flimsy. Some have commented that it’s difficult to remove the lid, but if you open the sipping hole, the lid unscrews on and off easily by releasing the vacuum seal. Another feature that sets it apart is that I can brew a 12-oz cup of coffee without the water overflowing, with room to spare. I have only positive things to say about this cup. It’s perfect and far superior to the others I’ve tried, including expensive popular name-brands.

This was my second purchase of this mug. I bought it for a friend for Christmas since I loved mine so much. This mug comes apart completely to clean. The two plastic rings come off, the inside of the lid comes off. The easiest travel mug to clean ever. It keeps my coffee nice and hot for hours with no need to temper the mug first, even though that might help. Leak proof *as long as you remember to put it all back together* twice I’ve grabbed my mug and not make sure it was reassembled correctly and ended up with hot coffee all over me. I check it now and don’t assume. Great product - only complaint is - I wish it was larger. But that a personal coffee issue.

Perfect size , easy to use and to clean, keeps drinks cold or hot as needed. I highly recommend this cup

bought this cup because i needed something to hold my hot coffee in when i go to school and paper cups just are messy and a disgrace if im honest. great thing about this cup is that it keeps my hot coffee hot for a very long time. by the time i finish it it is still warm but like not regular warm like more on the hot side of warm like if there was a spectrum it would be between the middle (which is warm) and the right (which is hot) and usually i finish it about an hour and a half after putting the hot coffee in. its so good that my dad even claims that it hold his coffee hot for around FOUR HOURS which is insane obviously. also it never leaks like once i dropped it in the hallway and it was so loud and embarrassing and this boy behind me picked it up and afterwards i had to walk in front of him for the next minute or so. i wanted to crawl into a ball and disintegrate, but guess what? it didnt even leak one drop. wow. the only downside which would be why i gave it four stars instead of five is that it is squeaky as hell. now, i know this is a stupid complaint but when it is 7am in the morning the last thing i want to hear while i twist the top on is a squeaky sound. like if you drag your finger on glass i HATE it. but, because this coffee cup has made so many of my terrible early mornings not that terrible, i will overlook this small inconvenience. i love you guardian collection by thermos 12 ounce stainless steel travel tumbler in blue and i hope that we can continue to share our mornings together for a very long time.

LOVEEEEE. I love that it's dishwasher safe, I LOVE the size - it's perfect for my morning tea and fits everywhere perfectly (car cupholders, backpack, lunch box, anywhere). It doesn't keep it hot for too too long, but it's perfect for me (I don't like my tea scorching hot anyways). Never had an issue with leaking either. Not to mention the color is gorgeous!!

Terrible, cumbersome lid design, so you have to remove the lid to unlock the mug for drinking. If it's unlocked, it leaks, and the locking mechanism falls out of the lid and into the drink. Garbage. Do not buy.

This is my second thermos Tumbler coffee mug I already own the 16 ounce one. what’s good about this size? It’s perfect for commuting, very reliable and it does not spill. I like the nonslip Texture they provide, it appears to be scratch proof because the paint is baked on which will provide years of use with a good looking exterior. The color says Matcha green, but it kind of looks like gray. If you don’t have anything green to compare it to. The price point is perfect. Compared to a lot of competitors. You are getting a quality Coffee Tumbler

Correcto

Me gustó mucho es muy practico y no tira líquidos si se cierra bien, el precio si es elevado pero creo que vale la pena

excelente tapa. buen tamaño para los espacios en coche y mochila. tapa anti derrame y con sello perfecto. lo puedes manipular con una mano. limpieza a mano o en maquina lava platos. color impecanle y muy bonito

Sella muy bien solo tiene un pequeño detalle como que se cayó y se abolló un poco pero fuera de eso es un termo increible

يحفظ الحرارة بشكل معقول زي ماقالو ٣ ساعات بس القهوه تسرب اذا ميلته استخدمته مرتين عبى ملابسي وانا متاكد انه مقفل بشكل ممتاز لكن تجربه سيئة وماعاد بشتري من نفس الشركة

فتحته للتنظيف وما عرفت ارجع اركبه،
