Customer Ratings & Reviews

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.

Perfect for keeping your coffee warm , especially if you find yourself distracted with chores and the like. You can set it to what ever temprature thst suits you the best

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.

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

Product looks great, size is perfect, and works so well.

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

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.

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.

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 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.

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.

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.

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

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

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

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.

Gives a wonderful cup of coffee at perfect temperature

a total must have. keeps my coffee hot for long time.
