Title: Leaks like a siev
Review: This mug is a joke. Not only do you have to hold the button in while you drink but it leaks when it is overturned. I returned mine and bought the OXO liquiseal mug (5 stars). It worked far better, no spill, and it's vaccum sealed stainless body kept my Joe warm for several hours. It clicks open and closed so you control when you want to close and seal it. Lid is a bit tough to clean but for the security of no spill in your car or bag it is worth the effort.
