I love the coldest Water bottle. It is stainless steel and so no BPA plastic you need to worry about. I drink water 99% of the time and am always bringing an insulated cup with me so that my ice water stays ice water as long as possible and stays cold. I decided to try this out because it has a way to close of the top unlike my insulated cups that have a straw out of the top and are not leak proof. Since I am carrying this around all day with me I would much rather have something I can close and know if I tip it upside down accidentally that I won’t have water all over. It works great at keeping my ice water cold and the ice ice as long as possible. I have not tried it with hot drinks to see if it would work that way or not.
