Customer Ratings & Reviews

Perfect size, keeps drinks at a nice temp. Different temps for different drinks. Mug battery life is ok but it you're a really slow drinker may not last.

It's been used every day, great at keeping your coffee warm or even hot if you like. Battery doesn't last whole day but good enough for the cup size

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 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.

This is a MUST for every HOT tea/coffee drinker! It's a perfect office gift.

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.

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.

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.

As the owner of both the black original and now the stainless steel version, the latter is my clear favorite. It does the same thing as the black, but it looks cooler doing it.

Very nice mom loved it and she says that she uses it daily

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

I bought this as a birthday gift for my husband. He loves it and uses it everyday. It's so convenient sitting on his desk and keeping his coffee at the perfect temperature all the time. And it washes really well too. You don't need to scrub it. Just rinse and it's clean again. And maybe because it's black, I don't see any coffee stain. I may consider buy one for myself.

I got this om a whim cuz i like gadgets. But it does keep my tea nice and warm at various temps as long as there is liquid in the cup. There is a tea timer in the app which is nice touch. Even tho you can color code it, i’d prefer to just name them. I have two of them.

Works as well as advertised. Keep in mind that you do not want to leave the drinks in there for too long as you are essentially cooking your drinks. They will develop some strange flavors after enough time. The app works fine, but the mug is completely unusable without it which is a bit of a negative. Also a tad expensive for what it does.

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.

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

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.

Got for my daughter who always likes her coffee hot while she's drinking a few cups during her work meetings. She loves it! So I decided to get one for myself BUT I use a Keurig coffee maker, always making an 8 oz size cup--problem is I like a lot of cream so I realize the 10 oz cup will be too full, need to get a 14 oz Ember mug! Hopefully it will be on a Deal of the Day soon!

Love the design and finish of this cup. High quality and saves me trips to the microwave.

The Ember keeps my coffee warm for at least an hour, which is the longest I have taken to drink a cup. Probably will last longer. However, 10 oz probably means up to the brim, and you wouldn't be able to drink it without spilling. But for 8 oz, it's great.
