The tumbler works well and we are enjoying our sampler of teas

These tumblers are really well insulated. Your tea stays warm for hours. Highly recommend!!

It's sturdy, easy to figure out and strains most loose tea leaves. Perfect for my travel and stays spill proof in my backpack keeping it warm a pretty long dam time

I am a teacher and in the afternoon I like to have a cup of tea while my students are at recess. I make it in this tumbler in the morning and it is still hot when I go to drink it! It is small enough to put in my bag and it does not leak at all. Just got one for my Mom as well!! Highly recommend.

I absolutely love this tumbler! It keeps my tea hot and it keeps the 99.9% of leaves out of my cup. I bought a bunch of tea samples and am now testing a new one out each morning with this tumbler.
