Title: They Work Great
Review: I bought 2 of these, one for me and 1 for my wife. We are both impressed with these. My wife is pregnant and takes hers and fills it with ice water, and when she wakes up in the morning there is still ice in it. I am going to buy 2 more of these for my parents. They do not leak and they do everything that they say they will do, so I'm not sure how there could be any bad reviews unless you just don't know how to clean your dishes properly.
