Review: This is the one! - 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.
Review: Reliable, Leakproof, and Easy to Maintain - This 12 oz flask is the perfect daily companion for both hot and iced coffee. This is an amazing size to get. I’ve put the "drip-proof" claim to the test by carrying it inside my backpack, and it is truly leakproof—not a single drop escaped onto my gear. The exterior features a matte finish that provides an excellent, grippy texture, making it feel very secure in my hand. When it comes to maintenance, cleaning is a breeze because the components break down into two or three separate parts, ensuring no coffee residue gets trapped in the lid. Whether I'm keeping a brew warm for hours or enjoying a cold drink, this flask performs consistently well. At this price point, other brands won’t come close to quality of this thermo mug. Highly recommended as i went through numerous leakproof tumblers until i found the Alta Series.

### ⭐⭐⭐⭐⭐ Solid durable tumbler
*by P***H on March 19, 2026*

Nice intermediate sized tumbler. The closing system is superior. I used to use Contigo but these always started to leak within a year. Keeps temperature well. Nice solid construction and the finish is very resilient. Have various of these.
