This is the best water bottle I have ever had! It keeps my water ice cold for a long time. The ice lasted even overnight. I haven’t tried a hot beverage in it yet but I am sure it will stay hot for hours!  I love the flip top and the way it locks to prevent leaks. Also the push button is an easy way to open it and the handle make it easy to carry it with me. This is a high quality product and I highly recommend it!
