Customer Ratings & Reviews

Was a great gift my pur big coffee drinker at home.

Got this for my mother for Christmas. She has literally used it everyday day since for her tea or hot chocolate. Mug always keeps it hot for her throughout the entire day. She hasn't used the app features yet but is satisfied with the default temperature.

One of the best warming mugs on the market. Worth the price. The app has gotten better and making sync with phone even easier. After I bought this, have 10 plus family and friends that made the purchase after using my mug. Love to set temps for drinking a latte or coffee. Just click purchase and you wont regret!

default temperature is 135 degrees. With the app, I upped temperature to 140 degrees. coffee is more enjoyable at my desired temperature. I did not think 5 degrees would be noticeable, but it is.

I need to start by saying I love these mugs. I love having steaming hot coffee from beginning to end. That being said they have one major caveat. These things break apart inside and they don’t last long. The bottom flakes off. Always stirring the coffee in a different mug before putting it in here and rinsing right away doesn’t seem to help. They make a stainless steel tumbler that’s a thousand times better. We’ve switch to those and have had no issues.

I love my Ember mug bought four as Vhristmas gifts including mug top.

This was a great purchase. I normally drink my coffee from a Yeti to keep it warm but on the weekends I enjoying drinking from a mug. Temp control is perfect!

I love this mug! It keeps my tea at the perfect temperature all afternoon! You can control the temperature you want it set at and it handles it from there! Highly recommend!

The price was great. I should have bought a cuo that holds more ounces. It works very well. It would be nice if the battery held out longer. That may be the reason it was on sale.

Battery life seems to be less than anticipated are’s 135 degrees, but as long as you’re using the coaster it’s amazing. Says not to use a metal spoon, as it would damage the ceramic coating... don’t really have a rubber or plastic spoon, so tough to mix in sugar/creme as needed.

Bought these for Christmas for me and my wife, we both enjoy our coffee to stsy at temp. Wasnt sure if i would enjoy these or not , and to my surprise they reslly do a great job , the app makes it nice to ajust your temp , i would recommend

We have two Ember smart mugs and an Ember travel mug, and we love them all. This one has a somewhat larger capacity than the original, which is nice since the bottom contains the battery and does not go as deep as you would think by looking at the cup. Great convenience for keeping your coffee warm.

Bought as a Christmas gift. My wife absolutely loves it. No more microwaving to heat up her coffee. Even after she puts some creamer in her coffee, still hot to the last drop.

Love, not having to reheat my tea in the microwave with this mug. Makes for a great gift also. I also love the bold color

Family was thrilled with the gift! They said they looked nice too.

Works as promised. Keeps the drink at the predetermined temperature.

My wife loves her cup, this is the second one that i have bought from Best Buy. She accidentally microwaved the first one (I strongly recommend you don't do this - lol). But the cups work great and the store was helpful.

Bought for my wife. We dont need any more mugs for her. She loves it. Chargers great and easy to use. The coffee/tea she warms up is always hot. Always.

A must for coffee drinkers! I normally sip on my coffee while enjoying some kind of bread. My biggest annoyance was my coffee getting cold. This is the answer. Keeps my coffee for a warm 142 degrees. You wont regret it.

Gives a wonderful cup of coffee at perfect temperature
