Guardian Collection by Stainless Steel Tumbler 12 Ounce, Matcha Green

After a few uses I notice it has a plast8c aftertaste with hot liquids.

It keeps hot drink warm for at least 4 to 5 hours. Haven't tested with cold

You have to let the tea or coffee get to the desired temperature and then close lid. It's scalding hot when you put close the lid. It will stay that way. I learned that the hard way and it was almost an hour later

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. Actualización: El segundo que pedi fue el verde, ambos estan muy lindos, el empaque del primero era mejor sin embargo llegó en mejor estado el segundo. Tienen diferente sistema de sellado, espero que el nuevo sea tan bueno como el anterior. Soy muy fan de lo mucho que conservan las temperaturas sobre todo en bebidas frias.

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.

Bonito e eficiente
