Customer Ratings & Reviews

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.

Ember is great. No more cold coffee....no more microwave reheating.

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.

Love my ember mug! Coffee and tea stays nice and hot!

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.

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!

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 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

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.

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

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

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.

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.

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

Bought this as a late Christmas present for myself. This mug works great for coffee and tea! Very pleased with how it keeps my beverage hot to the last sip. Works so well that my husband ordered one, too. We each picked a color so we can identify whose mug is whose.

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

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 don't like cold coffee! I spent the money to buy this cup, in the copper color, for me and my boyfriend. Even when a repair guy kept talking about whatever, my mind was on my coffee. When he finally left, my coffee was still hot. I was very pleased.
