    Was skeptical about this cup. I expected this to not work but was pleasantly surprised! Not only did it keep my coffee hot for 2 hours the cup itself never got hot! The cup has great weight. It’s not ceramic but has that perfect weight to it that makes it feel like it is. Absolutely love it. Want to get the travel mug now.

    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.

    This mug is great. Now my wife or I can have our coffee and chase our kiddos around without worrying about drinking cold coffee. Keeps the coffee hot for over an hour.

    Love my Ember Cup. Use it daily. It is so awesome! Makes my life so much better, and with a smile. It's a total pleasure, after reading or being on the computer for an hour, to reach over and have a cup of coffee, the perfect temperature! And this part is hard to believe but it tastes better when it's the perfect temperature, really! Did I mention I love my Ember.

    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.

    These e-cups are wonderful but they will spoil you. Unless I have my e-cup, nothing ever stays warm anymore.

    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.

    The only coffee cup I need.

    Love pretty much everything about this cup, I've used it every single day since I got it. The cup is built well, has a nice feel in your hands, I've never reached the end of the battery life, and the app is easy to use, though I only use the app rarely. Oh, and of course it keeps your coffee at the perfect temperature, which is what this product is all about.

    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

    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.

    Bought as gift for wife and I’ve heard nothing but great things about this product. She loves the fact she can control the temp from the palm of her hand and don’t have to worry about other means to keep it warm.

    Decided to give it a try and it is a life changer! Gone are the days of cold coffee. When work gets busy and you forget about your cup for a while you go back and it’s still the perfect temp. Notifications on your phone when your ideal temp is reached. Can not stress enough how amazing it is. Originally got one for work, and ended up getting my wife one and one for each of us at home too.

    Although I felt guilty spending the money I did for a “mug”, it turns out it’s not “just a mug”! I love my coffee, but sometimes I get distracted and it cools down. Not with this product. My ideal temperature is 128°, and my mug stays there until I’ve finished the last drop. Absolutely recommend getting one if you don’t drink your coffee fast enough to keep it warm to the last sip.
