    Life changing!

    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.

    Perfect way to keep your coffee hot to the last drop! No electric cords except where you keep the base plugged in! Plenty of battery time for morning coffee. Bought it for my wife for Mother's Day, and she has used it every day since! No problems; only smiles!! I recommend the larger size so the coffee doesn't go all the way to the top.

    Love it!!! Though it was more than I ever thought a mug should cost, I was given one as a gift. If you constantly suffer from having your coffee go cold, this mug is the one for you. It takes about 12 oz of coffee and will keep it drinking hot for hours. The only drawback I’ve had is occasionally it doesn’t connect to the app and I have to re-do it.

    default temperature is 135 degrees. With the app, I upped temperature to 140 degrees. coffee is more enjoyable at my desired temperature. I did not think 5 degrees would be noticeable, but it is.

    Got this for my mother for Christmas. She has literally used it everyday day since for her tea or hot chocolate. Mug always keeps it hot for her throughout the entire day. She hasn't used the app features yet but is satisfied with the default temperature.

    My wife loves her cup, this is the second one that i have bought from Best Buy. She accidentally microwaved the first one (I strongly recommend you don't do this - lol). But the cups work great and the store was helpful.

    One of the best warming mugs on the market. Worth the price. The app has gotten better and making sync with phone even easier. After I bought this, have 10 plus family and friends that made the purchase after using my mug. Love to set temps for drinking a latte or coffee. Just click purchase and you wont regret!

    The price was great. I should have bought a cuo that holds more ounces. It works very well. It would be nice if the battery held out longer. That may be the reason it was on sale.

    Battery life seems to be less than anticipated are’s 135 degrees, but as long as you’re using the coaster it’s amazing. Says not to use a metal spoon, as it would damage the ceramic coating... don’t really have a rubber or plastic spoon, so tough to mix in sugar/creme as needed.

    We have two Ember smart mugs and an Ember travel mug, and we love them all. This one has a somewhat larger capacity than the original, which is nice since the bottom contains the battery and does not go as deep as you would think by looking at the cup. Great convenience for keeping your coffee warm.

    I LOVE my Ember mug, but this is the second one i have purchased and it has already lost battery power in less than a year and 2 months. I am 2 months out of warranty on this one. So $150 is a steep price for a mug that only works for 1 year.

    No, I would not recommend this to a friend
