Title: Keeps coffee hot, but leaks.
Review: I love the look and feel of this travel mug. It keeps coffee hot for a couple of hours. However, it leaks. Every time I press the button to take a sip, hot coffee leaks out of the depressed button area. I thought it was how I was drinking it, but if I press the button and tip the cup slightly, I can reproduce the same problem.I really had high hopes for this mug, but I will be returning it.
