“Everyone in my family got one for the holidays. They drink every size and shape there is, so they have been using them non-stop! I am currently waiting for mine to come. In my opinion, this is the coolest invention ever!”
“Amazing! It really fits all sizes! The only thing I don't like about this item is the tumbler lid. When I first used it, the lid leaked and it leaked A LOT. I realized I didn't have the lid on tight enough and figured out that the lid is REALLY a tight fit. With a little finesse and some muscle, it goes on and doesn't leak. Other than that...this product is fantastic!”
