    Works great! Keeps my coffee or green tea at exactly the temperature that I prefer for the 60 to 90 minutes that I sometimes need to drink the full cup.

    I love this mug. I drink coffee slowly at my desk so it keeps it hot in between sips!

    So from the standpoint of keeping my coffee hot this is an awesome mug and I love it. The downside is buying it in white…there is no way to keep it sparkling white but it’s great and I use it nearly every day. It’s also a little pricey…find it on sale if you can.

    This mug functions beautifully, when it stays connected to my wife's phone. Occasionally, perhaps when it updates, it creates a problem to reconnect to her phone. It still works, but not fully functional until I can get it reconnected.

    I have owned 5 of these mugs and they are great for about the first year. A couple of them didnt last that long and I had to submit a warranty claim. Ember was good about the replacements but they have also deteriorated quickly. We do use them daily.

    I bought this mug as a present for my son because I already got one and I love it. I like my coffee hot and the mug has been the best solution so far.

    Great cup it keeps my drink hot for awhile the only issue was it didn’t have a lid if I wanted to run out with it but I got the separate lid for 14 dollars and it works great and looks nice on my kitchen

    This is the best coffee mug ever invented. It’s keep my coffee at an optimal temperature for 30-45 minutes which is more than enough to drink a nice cup of coffee or even have two. One of the best investments my wife has made for me our entire marriage

    I got this for my wife for Christmas and she can't get enough of it - she uses it for almost everything and it keeps drinks hot or warm for indefinite periods of time, so when you're running around in the morning you don't have to worry about your coffee going room temperature.

    Valentines Day gift and absolutely love it! I generally pour a cup of coffee at the beginning of a call and sip throughout. The problem is that it is always cold by the end of the call. This keeps it warm all day on the saucer and if I am away in a separate room, up to 1.5 hours off the saucer. Perfect for the busy executive schedule.

    Great concept- but...

    Great concept! But if you have a few sips of coffee left in the cup, it does tend to taste burnt, and it creates a strange film at the top of the liquid. BUT - If you have the mug more than 1/2 full and leave for 20 mins or so, the beverage does stay nice and hot when you get back...

    No, I would not recommend this to a friend

    Great for the winter or every day use! Don’t you hate when your coffee or tea gets cold, well you don’t have to worry about that anymore if you get one of these. The charge is great and it keeps it at a great temp

    This is my second ember. I found the smaller size a bit too small since I use milk. I still use it while the bigger one is charging. I am very happy that my coffee stays hot while I do housework or am on the computer. Saves me multiple trips to the microwave and the Ember coffee flavor doesn't degrade as it might with the microwave.

    My wife can’t say enough about how much she likes this cup. With two small boys, her tea and mine would be cold by the time we got back to it after addressing the need of the moment. Not anymore. We take care of the kids and the tea/coffee is still at the right temperature.

    I thought this was going to be a pointless expense, but I love it since the first cup of coffee… I’m always easily distracted and by the time I want to finish my cup of coffee before, it was very cold… not with the ember, I gasp and smile, there it was, my cup of coffee, at the perfect temperature and totally worth it.
