I drink hot beverages throughout the day and this thermo tumbler does an excellent job at keeping the temperature. In terms of application, when drinking, no leaks.
When traveling, great little size to fit in regular cup-holders and bags. The lid seals tight, so again no leaks.
For the intended use, it's perfect. I have a Keurig coffee maker, and I usually make an 8 oz cup of coffee which this thing holds with room for milk.
I like the bamboo feel and it's easy on the eyes too, like a little piece of furniture. LOL
Favorite feature after a few days of use? the hot temperature of the drink after even a few hours.
At the end of the work day yesterday I topped it off with hot water, went out to dinner and movie and then pulled it out of my laptop bag and took a sip of the tea.
Yep, the drink was still hot. A pleasant surprise and a real treat!
