Customer Ratings & Reviews

If you are a coffee drinker and love hot coffee, then this is the best device you can buy and it's well worth it. Be advised, this cup will only work with iPhone or iPad. Does not work worth a on Samsung Galaxy.

Bought this cup for my daughter-in-law for Christmas. Had occasion to visit her and saw she was using the cup. She loves it and uses it daily. I plan on buying one for husband soon.

Love this mug! Kept my coffee warm for hours!! Weird at first to expect to pick up my coffee and think it’s going to be cool and it’s just as warm as it was an hour ago. Fantastic!!

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.

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.

These are the greatest mugs, I’ve had one for a few years and decided to get another color. I’m a slow coffee/tea drinker and I love how the Ember mugs keeps it my perfect temperature.

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

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

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.

Excellent buy, definitely would recommend, keeps my coffee nice and hot all day while I work, works great for any home office.

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

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.

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.

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.

Love it! Super convenien. Love the app. Works well.

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.

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.

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

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.

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.
