Customer Ratings & Reviews

Over time the mug does not maintain the temperature set for the coffee. I think the battery is wearing out. Seems like it is wearing out awfully fast.

This is a great mug! It does stain though so be careful and after two years it just died. Going to write support

Although i love this cup and its “on the go” features, the only thing i would change it how fast it heats up. It can take some time to get a warm cup of tea or coffee

Is amazing nice warm cup for drinking coffee or tea I like color very much I like 14 size for cappuccino and regular coffee siz 10

I purchased the white mug. I was worried the color might show coffee/tea stains, but it does not. The lip is nice and thin, The mug will keep liquids warm for about 1.5 hrs., wish it was a little long, but I just keep the charger next to my work area. Just have to remember to place the mug on the charger and not on my desk. Overall I enjoy the warm cup of coffee. I little hard to justify cost for an average gift, but for a spouse, partner, or self indulgence very nice.

Easy to use and keeps beverages warm. But if coffee was kept in it for awhile, it looses its taste and creamer in the coffee makes it turn bad. So I don’t use it with my coffee, and been using with tea and other hot beverages.

Great concept. We have two of these and one is malfunctioning after 2 years and customer support is horrific (slow and unresponsive). When working it’s a great product but definitely a luxury item. Glad to get rid of our other mugs.

Love using this mug on weekend mornings when im wanting to sip my coffee slowly. Love the app integration and cusromization of the led light.

I tried to like it but I bought multiple from different vendors including Best Buy and had to return them. If you get a good one then it's decent at best, one of them wouldn't charge, one didn't report to the app, etc. Stupid stuff and Ember support was no help so I decided to go back to a normal mug. You also have to be extremely careful washing it due to the electronics. Too much work for the result.

Wife loves it. She has the travel. Mug as well but loves the cup because she can smell the flavor of the coffee.

I like the mug's function, but I subtract one star for the wall wart style power transformer. They could easily and cheaply have pushed the transformer a few inches closer to the mug and then included a standard AC cord and plug.

I own the tall Ember Coffee thermos (gift from my son) and it works great especially if you are an avid coffee drinker such as myself. So I bought this Ember Coffee Cup for my son for Christmas and he really likes it as well. It beats having to reheat your coffee ten times.

I like this cup very much but if you get the bottom wet, dry it immediately. The rings on the bottom will turn green and the material will start to erode if they are not get completely dry. It's on odd requirement for something destined to hold liquid.

Nice concept but falls short. It’s only good for up to an hour and if you’re at your desk all morning, it just fails for that time.

My family love the gift! I bought the black one for my brother in law and white for my sister. Good Xmas gift

Works better than I thought and the battery life is really good.

Nice cup but very small. It looks bigger than expected but does the job.

Awesome profuct at a great price. I bought 3 if them fir Christmas presents and they were recieved with glee.

I purchased this as a replacement for an original ember mug and am very satisfied. Connectivity and battery life both seem improved. This does everything I want it to do. It is used multiple times every day with no issue at all. Highly recommended.

I love this mug only thing is it doesn’t stay warm for more than 20 min. I wish it would keep things warm a little longer only because I drink a lot of tea and like to use this mug to pour from my bigger one.
