Title: TOO MUCH EFFORT
Review: I got this mug after reading all the great reviews on Amazon, and it's been a big let down for me. I don't think this mug keeps the coffee that hot; mine leaked when I turned it upside-down; but the worst part of it all was that, because of the fact that it is called a "spill-proof mug," the mug always stays closed. Some people might like that aspect. However, the downside is that you have to push the red button EVERY TIME (and keep it pressed every time) that you want to take a sip of coffee. And the button is not that easy to push. There is no locking mechanism to keep it open indefinitely. To me, it defeats the purpose of having coffee readily on hand to drink. It also makes it hard to hold the cup, because you have to hold it at the very top so you can push the button every time. If that doesn't bother you, then this should be an ok purchase. I don't like it at all.
Is the review positive or negative?
