“I have gave the lid a four-star because it is nice to be able to clean every part of the lid and straw. I am not thrilled with the function of the straw. It is very hard to get it on tight enough that I don't suck air while using it. I absolutely love the 40 oz tumbler with the lid and straw it came with. In hindsight I think I should have kept the lid it came with and replace it more often. (since I can't get in there to clean it like I want to.)”
