    This Ember temp-controlled mug is a great value and comes in very handy on cold days when you don't have time to boil water!

    Today is the last day I can return this. Apparently I bought this 59 days ago and the cup has melted on its own and it’s not working anymore

    Too complicated

    I bought this for my wife for Christmas hoping it would make her life just a little nicer by keeping her coffee warm while she completes all of the tasks she takes care of every morning. Instead, this mug has just become another source of frustration. The switch to turn this thing off and on is located on the bottom of the mug instead of on the outside of the cup where the user can see it and use it while filled with steaming hot coffee. I don't know about you but the last thing I want to do is try and keep a piping hot cup of coffee from spilling on me while trying to balance it above my head while fumbling around with a switch on the bottom of the cup. In addition to re-locating the switch to the side of the cup they should change it to a sliding type switch that is either on or off instead of the type of switch currently employed which requires one to repeatedly press the switch a number of times to turn it on and a different number of times to turn it off. Likewise, you shouldn't have to put an app on your phone in order to set the temperature. Just put a slider switch on the side of the cup. Bottom line; they made this thing way more complicated than it has to be. Currently, it takes anywhere from five to ten minutes to get this cup to pair with your phone and by then, your coffee is already cold. I guess we can repurpose this thing into another boat anchor. Caveat emptor.

    Must have the app to make it work completely. Doesn't keep the beverage hot for a long extended time. Has to be hand washed. Bottom line, a really very high priced coffee mug.

    Pleasantly surprised, but poor software

    I picked up this Ember mug on a special deal not hoping for much. In reality, I have been pleasantly surprised with my purchase because it lets me enjoy my hot drinks for much much longer than I normally would. The only issue I have with this product is that the Ember software is pretty annoying to setup properly. Pro tip for Google phone/Android users: to properly pair your Ember mug with your phone, connect it via Bluetooth FIRST and THEN connect using the app.

    I got this last Christmas and loved it, but this product lasted only about 5 months. By May I could no longer open the app and it stopped heating. Will not buy this brand again.

    If you are considering an Ember mug, I would recommend either the 10 OZ or the travel mug. the 14 OZ does not keep your second cup hot. the battery is too small even though it's on the charger. I do love the travel mug if you keep it on the charger,

    Battery doesn't last for when 1 cup of coffee. Returned. If the battery would last for 3 mugs or even 2... It would be amazing!

    After a little after a year, the mug fails to detect my hot coffee. It keeps saying 'Empty' and stop working. Emailed customer service and it went nowhere, asking the same questions over and over again even though I've answered them. Very dissapointed.

    A better option than the 12 oz version and with a thicker wall which hopefully makes it more durable

    I wish it was bigger since you really can only put 12 oz. in the mug. Other than that I like it.
