I bought my travelmug2 a year and a half ago. I have used it every. single. day. I can't ever use another travel mug now.  I have the mug for home also. I bought an extra charger that sits on my desk at work. My commute to work is about 45 minutes and my coffee is wonderful the whole time. The only thing is I wish it would refill itself lol.  I've bought Ember travel mugs now for my mom and best friend. I got back on the website to order the new travel charger and decided I should leave my review. The ember travel mug is a daily necessity for me and I absolutely love it! I've never had an ounce of trouble with it ever. Very dependable and sturdy. I've dropped it twice and both times I cringed, but it hardly had a scratch and you'd never know it was dropped. Definitely buy one for yourself and a holiday gift for friends!
