Customer Ratings & Reviews

No more sipping cold coffee or tea. This is the perfect size for those who use a Keurig to make their coffee, there is enough room left in the mug to add creamer if prefered.

Great mug, exceeded expectations for ability to keep coffee and tea to the desired temperature!

Absolutely love my Ember. I love having tea but often times never get to finish my cup before getting cold, now with the ember i never have to worry about it getting cold. More importantly can always have to perfect temperature for my drinks to really ensure full flavor.

My first purchase was 2 years ago. My other half loves it so much I bought another for our friend and office.

Great for the winter or every day use! Don’t you hate when your coffee or tea gets cold, well you don’t have to worry about that anymore if you get one of these. The charge is great and it keeps it at a great temp

Although I felt guilty spending the money I did for a “mug”, it turns out it’s not “just a mug”! I love my coffee, but sometimes I get distracted and it cools down. Not with this product. My ideal temperature is 128°, and my mug stays there until I’ve finished the last drop. Absolutely recommend getting one if you don’t drink your coffee fast enough to keep it warm to the last sip.

Decided to give it a try and it is a life changer! Gone are the days of cold coffee. When work gets busy and you forget about your cup for a while you go back and it’s still the perfect temp. Notifications on your phone when your ideal temp is reached. Can not stress enough how amazing it is. Originally got one for work, and ended up getting my wife one and one for each of us at home too.

Love this cup. I enjoy these little luxuries. It is more pricer than the other colors but this color makes me happier than the other ones. I did buy the black one for my husband and he loves it. Keeps the drinks warm. Just don't microwave it!

Great item. Heavy duty. Could use longer charge…an hour and fifteen feels short, especially if you have more than one cup at a steady pace…not long enough, believe it or not. The price is the hardest thing to swallow and i don’t think a better battery is out of the question for this price.

This was the best purchase i ever made. My coffee was constantly going cold after i make it and have to care for customers. Now it stays hot to the perfect temp all day.

These mugs would be incredible for those who make a pot of coffee for the day and would recommend it to those friends. If you are using K-Cups, you must get this 14oz size over the 10oz to make it justified (we had to get this one after purchasing the 10oz). If it were up to me, I would still make it a little bigger. Other than that it works well.

Works great! Keeps my coffee or green tea at exactly the temperature that I prefer for the 60 to 90 minutes that I sometimes need to drink the full cup.

I’m in love with my Ember! Hot beverages going cold mid-cup, was a huge pet peeve of mine. Discovering this mug solved that issue and I love that I can take my teatime as slow as I want! Highly recommend and a great gift for coffee/tea lovers.

Love it!!! Though it was more than I ever thought a mug should cost, I was given one as a gift. If you constantly suffer from having your coffee go cold, this mug is the one for you. It takes about 12 oz of coffee and will keep it drinking hot for hours. The only drawback I’ve had is occasionally it doesn’t connect to the app and I have to re-do it.

I'm writing this for a chance to win a $400 gift card lol Cool cup, though

Perfect way to keep your coffee hot to the last drop! No electric cords except where you keep the base plugged in! Plenty of battery time for morning coffee. Bought it for my wife for Mother's Day, and she has used it every day since! No problems; only smiles!! I recommend the larger size so the coffee doesn't go all the way to the top.

I definitely needed the 14 oz. 14 oz right to the top so not enough room to tilt it to drink The liquid starts cooling immediately, but if you let your coffee set around this is a good option as the last drop will still be hot, but not as hot as when you poured it.

A bit heavy, this mug keeps my drinks warm. It is easy to pair by bluetooth and lasts a good amount of time. The app is user-friendly and has a lot of cool preset features for everyone's hot drink needs

Working from home you can easily forgot your hot cup of joe. But nothing to worry about here this cup will keep it at the perfect drinking temperature making sure not to get that burnt coffee taste

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!
