    Liked the concept and gave it as a gift, however the recipient didn't have a desk to keep the warmer plugged in.

    The Ember mug is a great concept. And when it works. It really lives up to the idea. But unfortunately this mug suffers from tremendously incompitent software. This cup worked on day one, but every day afterwards we could never get it to work. The app wouldn't open anymore. Even reinstalling it would not solve the problem. The mug unpaired itself. It turned this great birthday present into just a normal cup. Upon looking at the Google play store reviews for the companion app (which you need for the heating to work) you'd find a 1 star rating with thousands of people having the same issues I was. Cannot reccomend until the software is fixed.

    Great idea but battery life is not quite what I was hoping. Bought for my wife for a Christmas present and she likes it but disappointed in the battery life.

    I bought the black Ember mug for my best friend as a graduation gift. He loves it and I am planning to buy one for myself. I don’t drink my coffee fast in the morning so this is perfect to have at my desk!

    I have really enjoyed it. Not certain that I will purchase it again when Walmart has something similar. But I do like it. One of my favorite things is that when the cup is empty it shuts off which is extremely important to me.

    This product is great! Works as expected. I originally ordered the smaller size but returned it, highly suggest going with the 10z size. Sure does beat having to microwave you coffee in morning to keep it warm.
