Customer Ratings & Reviews

As advertised keeps coffee at a specific temp that is flexible to what you want, easy to use. Downside is you cannot use regular silverware, it can scratch the coating. I use wooden stirrers and it works fine.

This cup is incredible!! Any serious coffee drinker should get one. Your coffee stays hot for about an hour before it needs to be charged. If a person works, you can connect the plate to electricity from your desk, you can continually have HOT coffee all day.

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.

Perfect for keeping your coffee warm while at the office or home.

A little costly, but worth it. Now I never have to worry of my tea or coffee going cold.

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

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.

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

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

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.

This mug is wonderful. Every cup of coffee stays at just the right temperature and the cup recharges quickly. Took one star off because it will not stay linked to the Ember app.

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.

Works great, keep my coffe hot all the time, just work great for me

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.

The design and how the mug works is well done, being simple and easy to use. As in, you aren't having to go through the annoyance of having to plug this in. You just place it on its mat at any angle and the pins will pick up the charge on the circular tracks wherever they are. The mug has a nice solid, sealed feel to it and the charger is very light weight.

This product does really keep the coffee hotter for a long time. It really works.

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.

Now I don't have to reheat my morning cup of coffee in the microwave. This Ember keeps two cups at the right temperature all morning long. I have to remember to place it on the charger each night so it is fully charged in the morning.

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!

I purchased this as a Deal of the Day at a reasonable price. It does take time to get use to it. I'm satisfied with this Ember Smart Mug. I just needed something to keep my Lattes warmer a little longer. I like the 14oz size so there's room to stir without splashing it all over.
