Customer Ratings & Reviews

I have enjoyed using this but i really didn't need it. It works as designed and keeps my coffee perfectly warm in the morning. I recommend it as a cool gift for someone who wouldn't treat themselves but they love coffee or tea.

Great cup, bought it for my wife she uses it everyday

Pretty mug. Liking how it keeps coffee and tea warm. My issue is the length of time it takes to charge and the amount of time it holds the liquid warm at temp. It would be nice if there was a notification alert to when the cup is about to stop keeping my coffee warm due to battery dying. I’d also like the cup to have a brighter light to indicate when it’s charging or when it’s dying. Currently to see the light, the current kitchen lights need to be turned off. The indicator light is so far at the bottom, I need to bend down to see it in the day or turn off the lights. Also, the cup is not dishwasher safe. I’m a lazy man and when a cup like this is mixed with regular dishes, I want to grab all dirty dishes and put it in the dishwasher. Now I have to take my sweet time and identify which one of these don’t belong. It’s a fun game. You should try it!

Love the mug, keeps it nice and warm at the temperature I want. Love that it it’s pretty big since I do drink plenty of coffee in the morning. Mug actually has stopped working couple days ago and I’ve had it for 4 months, contacted Ember they will be sending out another mug since it just completely stopped working, doesn’t light up or anything. But other than that works great, keeps it super hot if I put it on highest which I love since I look forward to my coffee and I work from home so I spend all morning drinking it. Love the purchase.

I love HOT coffee through the last cup and this makes that happen, does not "cook" the coffee and app gives me ability to adjust. Handle is perfect, and rim is not thick so that is perfect too........only thing is that is hold a cup size not a mug size of quantity, but for my expresso maker its perfect.

Very cool item if you like to keep your coffee hot,

Product works well. Disappointed in the size of the cup

Ease of use (of accompanying phone app) exceeded expectation.

Keeps my coffee hot for a long time. Very easy to use

I heard about this mug years ago and laughed it off. There was sale so I purchased lol, I use my Ember Smart Mug daily! The app is easy to use. The mug keeps liquids hot. I have put cold liquid and it heats up to 135 degrees. I wish the larger 14 oz. was available for purchase. I originally ordered gold but exchange for copper but both look great.

Wife LOVES this mug. She was reheating her coffee 3+ times before finishing a single cup. No more. Works perfectly. She did experience an issue after 7 months of use; customer service was great and handled the situation in a way that exceeded expectations. I bought three more as gifts for friends and family since.

great cup - nice to have coffee and tea stay i the perfect temp rage for a long time... no more last two gulps of bitter tepid coffee

Works as advertised… kinda pricey but great quality. Makes it worth the money

My wife bought me this mug for Christmas. I love it! My coffee constantly stays hot.

The perfect gift for the coffee drinkers in your life. Easy to use, easy to clean and provides a clean design throughout.

I have had this mug for almost 2 years and have gifted to friends and family. Best invention ever! I love how pretty the copper is as well as how well the product works!

I love it and hate it all at the same time. It is expensive for a mug that seems to last about a year, but it is wonderful to have piping hot coffee for an hour or more. We’ve had 4 of them. 1 just quit, 1 the finish was coming off, 1 got fused on the bottom and stopped working. However when it works, it’s great. My suggestion is to be kind to the finish with nothing abrasive to clean it. Make sure the bottom is dry when putting it on the charger. It should bring you many months of joy if you like your coffee hot. This one was bought as a replacement.

I bought this mug for my father-in-law. He loves it! Uses it every morning and is able to sip on his coffee throughout the day.

My husband and I are serious coffee drinkers, and had recently taken to nuking our coffee to keep it hot enough. These cups were an extravagant gift to ourselves and we're thoroughly enjoying them. Our experience has been great, up to and including using the Android app to control temperature and a couple other features. Very pleased. I've ordered another so that I can keep one cup charging while one's in use -- again, very serious coffee drinker here.

Fantastic product. Used it everyday for 6 months and then the charging station failed. Also, get the larger size. You will thank me.
