Customer Ratings & Reviews

Gave this as a gift to my wife who loves having her coffee hot. Normally she would set her coffee down and when she got back to it, it wouldn't be hot enough. This would cause her to microwave her coffee 4-5 times. With the Ember, she places it on the charging coaster (which keeps it going continuously) and she can sip away all morning long.

Awesome for someone who likes their coffee hot! Saving a lot of wear and tear on the microwave! If you drink coffee through the morning, it's best to use the recharging stand as a coaster, since the battery lasts about an hour and a half. Highly recommend.

I like the concept of this mug. Overall it has worked well, 9/10 times getting it right that there is a beverage in my cup. My I main complaint is thst i feel tied to the charger. 80 minutes goes by faster than you’s think.

I wasn’t sure if I would actually use this but I use it everyday at work!! I set my temperature on the app & I don’t have to worry about my coffee getting cold!

The Ember Mug is a great gift for anyone anyone who enjoys their drinks to be hot, and to stay that way. They provide you with a nicely-sized cup which not only comes with an app to customize & set your own temperature, but it also has built in thermal technology to keep your hands safe & store all of the heat inside.

Love this so much. No longer have to reheat cold coffee. Very easy to control, a great gift for coffee/tea drinkers.

This is my 3rd mug in about 6 years. I use them heavily so the battery starts to wear out after about 2 years. I've never had any problems with the app, although once I sync and set my preferences, I never use the app again. I don't understand why you would want or need to. I have found the Ember mugs to be exceptionally reliable and have recommended to many family and friends.

Works as advertised! Two recommendations: 1 needs longer lasting battery 2 or provide extra charging plate so you can charge in multiple locations.

Love the mug, definitely keeps coffee hot. Not sure if my coffee maker is off or if this mug doesn’t actually hold 14oz. If I brew a 12oz cup it’s at the brim. Had it for a month and a half now with zero issues

This thing keeps my coffee at a perfect 140F for me. Only problem is if my phone is away from the mug it shuts off. Now i use this at my office job and sometimes i need to step away from my phone and need my phone. So when i walk away the mug and app disconnect and it shuts off. Its an annoying thing that just happens.

The Ember mugs are excellent. They perfectly solve the problem of trying to catch your hot drink during the short window of perfect drinkability before it gets too cool. Just set your preferred temperature using the app. It might take a while for you to learn through experimentation what your preferred temperature is, but one you know, you know. There are two sizes. My first size was the 10oz. mug. It is slightly too small to hold all of a Nespresso Virtuo coffee, and barely holds 10oz. from a Keurig. I was pleased when they launched this 14oz. size. It suits all my needs so I recommend paying the premium for the larger cup. My first cups where white. They tend to stain after some use. Therefore you might be more satisfied with a black or blue mug. Be careful with the charging base. The two little electrical elements that power the cup are fragile. Place the cup gently on the base. Don’t set it down too aggressively or you can break them. You can buy a new charging base but it isn’t cheap.

Love having my coffee always the temp I want! I never have to top off the cup to keep it warm!

Bought for my mother in law as a gift. She loves her coffee scalding hot so she loves this cup. She could go take a shower and when she comes back to her coffee mug, the coffee is still hot! If you drink lots of coffee be sure to get the 14oz. It doesn’t look big so I can’t imagine how the 10oz compares.

Great deal. Keeps coffee hot, ego high aside wife’s white one.

I never thought I needed this kind of mug. But it is amazing! Side tracked and forgot about your coffee? No problem. This mug keeps it warm and fresh, as though you just poured it. Easy to clean and love the color.

I haven't used anything else for my Chai Lattes since I got this mug. It keeps my latte warm all evening...no longer have to re-heat in the microwave when it gets too cool. Perfect for me! Might have to get another one for my regular and herbal teas!!!

Like the title states, it is expensive for what it does, but it does what it is supposed to do well. App is easy to to use and the mug holds a charge well. Only cons is price, and isnt dishwasher safe.

Worked great for about 6 months! It started not charging the mug would only charge sometimes other times it would say charged then would just shut off.

Expensive, let me say that first. If BB did not have it on sale I would have passed on it but it does keep my coffee hot! The mobile app is a great plus as well to control the temp settings. Easy to charge, easy to rinse, and clean for the next use! Not throwing it in the dishwasher for sure!

Bought as a Christmas gift for my wife, she loves being to keep her coffee warm in the mornings. Only downside is they should include from the factory a lid for it to extend battery life and help with spills.
