Overpriced tumbler
Purchased because visually it looked like it would hold more than my current tumbler. My beverage is no warmer or colder than when used in my other container. It does not meet my satisfaction. Add to that the closing device keeps falling out. Waste of money.

OMG loved it
I love it since the first time I used it. My coffee is so hot all the time. Sometimes I make my coffee but don’t have time to drink it, but when I get back to my car my coffee still feels so hot, and make me so happy, love my new thermo guardian expresso.

Best cup in a long time
I haven't had a cup this good in a long time. The lids can be taken apart for thorough cleaning, and it keeps hot drinks hot for up to 3 hours and warm for around 6 hours, while keeping cold drinks cool for much longer. It also appears to be scratch-resistant and durable, and doesn't leak when the lock is engaged
