    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.

    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.

    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.

    Warms well. Battery is long lasting. No complaints at all. Only thing is that the mug takes a while to warm the water, but working from home gives me plenty of time to wait.

    Looks great and does it's job. But be careful about about leaving a sip in the mug for a longer time, it will evaporate and leave a tough stain

    It is nice to have such a cup to keep tea or coffee hot. But its reliability needs to be improved. There have been a quite a few times there is drink in the cop but the cup cannot turn on automatically
