I received this Thermos mug as a gift a little over a year ago. I've been very satisfied with the insulation power and usually leak-free top (I've had a couple of small leaks, but I may have filled the cup a little past the max-fill line). The exterior coating, however, is unacceptable. The coating started to wear off of the edge below the top after only a short while, but it was fairly contained. Now, a large region at the top of the mug is flaking off. I can scrape the coating off with my fingernail with little effort. I find bits of the coating on other containers in my food bag, I find flakes on my fingers after holding the cup, etc. It's unacceptable, I shouldn't have to worry about ingesting whatever paint / coating Thermos used. I haven't been hard on this mug - always gentle hand washing, no harsh storage / use environment.
The only thermal mug I've found that doesn't pick up residual odors or flavors. My coffee tastes like coffee -- hot, hot coffee! It's pricey but worth it, as I'm not buying coffee at work anymore, so the mug paid for itself relatively quickly. Great product!
This is my new favorite travel mug. It looks good, fits perfectly into the cup holder in my car and keeps my coffee HOT. One day I filled it at 7:30 AM, but left it on the counter instead of taking it with me. When I returned, about six hours later, my coffee was still hot. Ten hours later it was still warm. I love it!
