Title: Not worth the price
Review: After reading the great reviews, I decided to buy 2 of these. 1. They don't keep my coffee hot half as long as my Primus mug does and 2. You have to hold in the button in order for the liquid to come out. I understand that it's supposed to prevent spills but there should be an option to keep it open. Also the fact that there is no reservoir on the top is an issue. Again, I realize it's supposed to make for easier cleaning but the first few sips (when the coffee is still hot), you can't really 'test' the temp - it's all or nothing and you just have to hope it doesn't burn you.
