Customer Ratings & Reviews

I have bought two of these now and they work well. If you give to someone that uses the microwave to heat their coffee hide or unplug it. They will quickly burn the circuits and no longer work.

My Mother-In-Law is still thanking me for this super amazing coffee cup!

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.

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.

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 my Ember Cup. Use it daily. It is so awesome! Makes my life so much better, and with a smile. It's a total pleasure, after reading or being on the computer for an hour, to reach over and have a cup of coffee, the perfect temperature! And this part is hard to believe but it tastes better when it's the perfect temperature, really! Did I mention I love my Ember.

Great cup! Everything works well and is easy to use. My only complaint ( and it’s mine, not the manufacturer) is that the cup is too small! Should have bought the bigger one!!!

Love this mug! Keeps my drink hot to the last sip.

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 awesome gift for any hot drink lover. While it is alittle pricey, the product itself is good quality. The app is easy to use since you only have to set the temperature once and then the cup heats to that temp each time its turned on.

Was skeptical about this cup. I expected this to not work but was pleasantly surprised! Not only did it keep my coffee hot for 2 hours the cup itself never got hot! The cup has great weight. It’s not ceramic but has that perfect weight to it that makes it feel like it is. Absolutely love it. Want to get the travel mug now.

Easy to use and looks and works great. A tad on the spendy side however.

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.

Love pretty much everything about this cup, I've used it every single day since I got it. The cup is built well, has a nice feel in your hands, I've never reached the end of the battery life, and the app is easy to use, though I only use the app rarely. Oh, and of course it keeps your coffee at the perfect temperature, which is what this product is all about.

Keeps drinks warm! 1234567890123456789012345678901

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.

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.

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.

I bought this cup for my wife. She likes to take her time drinking her coffee and latte. She would usually have to microwave her cup two or three times to keep it hot. This cup does the trick! Keeps her coffee nice and hot, 145*, for hours! You can adjust the target temp to your preference but it tops out at 145. Great cup and has held up perfectly since purchase almost 6 months ago.

Great coffee cup…Fast charging and easy to use with app… love it!
