I truly love my Tervis Tumblr. my favorite thing about this Tumblr is how easy it is to clean and how durable it is. As a busy teacher, the last thing I want to do is come home and worry about disinfecting and cleaning my water bottle by hand. In addition, I really appreciate how durable it is. Due to my own clumsy nature, I am constantly accidentally dropping this, and it has yet to break on me. I have tried many water bottles, and this is the one that has stood the tests of time – and the tests of a hectic classroom environment! 

I’ve had several of these and the lid eventually begins to leak after 3-4 months. Not sure if lid gasket wears out or what. Becomes a dribble bottle. Also, the round material on the inside of the lid, that fits over the whole, begins to discolor like with a mildew type stain, that I have tried to remove with no luck. I buy new lids because of this unknown stain.
