I love this cup! I have had many different types of keep-cups and this is the first cup that does not leak at all.... ever! I thought that pressing the button to drink might get annoying after a while but it is no bother. The cup also keeps your coffee or tea hot or your iced drink cold for several hours. And it's easy to clean as the internal mechanism is moveable and allows fairly easy access and cleaning. I would recommend this cup to anyone and everyone!
