Great cup keeps my coffee or tea hot for at least 4hours

This is the best mug ever. Gave it to my husband for his birthday. He thought, oh great, another mug. But it's all he uses now. It keeps his coffee hot while he works. He just loves it.

Keeps my beverage at the temp I like consistently.

Not really impressed with this mug. First, I think it should hold more and second, the highest temp is 140 degrees...I prefer higher. That said, it is built solid and after several weeks using it, no problems

Android app continuously disconnects. Mug is awesome but everyone I know who has this and the android app has issues. I have to re-pair it if I want to use the app.

The cup works great, it keeps my coffee hot all day while on the coaster. The cup uses an app to let you configure your drink temperature and you can create profiles for drink types with different temperatures. But the android app is garbage. Read the reviews on the play store before you buy the cup. I had to restart my phone three times for the initial pairing to work. During the first week of usage I was only able to change the temperature once without having to restart my phone. I finally gave up and set the cup to one temperature and uninstalled the app. Overall I like the cup by itself and if you dont need to constantly change the temperature it works great.

Does a great job of keeping coffee hot for over an hour!

Perfect to warm up my tea or coffee every morning!

Easy for my mom to use after the app was installed. Heats to the right temperature and eliminates the burnt coffee on the stove.

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.

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.

I bought this as a gift. They told me they never used it. It's been 2 years. I want it back.

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.

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.

This device is useless as it is a high maintenance as you have to recharge it frequently to reused the heated cup. Each charge can only maintain the beverage in hot status for 60 min.

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.

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

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 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.

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
