Customer Ratings & Reviews

Bought this as a gift for a family member for Christmas, and the recipient really likes it for their tea. It is very well insulated on the outside so you don't burn your hands holding the mug like some others. Only complaint is that the battery life isn't the longest, but I saw that the lid you can buy may extend it to a certain extent, so that may be worth a try.

Christmas present for the Wife. She has been wanting one for a pretty long time. Seen a few reviews showing that the interior coating coming off and my only guess for the reason for that is that maybe they used a frother. Anyways this only gets hand washed and it is performing like an absolute champ. Do wish that they had a 20oz that was not the tumbler though.

Oled has been a game changer for a person who likes their coffee really hot.

My wife loves this. She always takes forever to drink her coffee or tea so I got her this so it never gets cold or lets her beverage go to waste.

Love this one of the best invention ever made use mine every nite

Love that it keeps my beverages warm. Easy to use and keep clean.

My wife loves it! She drinks her coffee slowly and it stays warm!

I would not consider living a life without this thing. We drink coffee every morning and drink tea once per week. You know how it sucks when hot beverages start to go cold? Welp for $150 you never have to experience that again!

It was a great gift! Keeps everything warm and is very easy to use.

Was surprised that I drink less coffee. No dumping cold coffee anymore. A little $$$ but still pleasantly pleased

It's a nice mug that may keep your coffee warm, this is for someone that needs it for additional hour (or 2 if you're pushing it) of good coffee (or tea, whatever you prefer). However, the battery isn't that last-longing. You have to charge it every usage. and that takes around 2-5 hours depending your habits and how often you charge your mug. If I have to be honest, I think you're better off with a double-insulated tumbler/mug that may keep your drink warm up to 5-8 hours a day.

Keeps everything warm. Does what it says it does. It’s good for one cup, so kind of sucks to refill if you drink a lot.

I love, love, love this cup. I can't tell you how many times I get pulled away, come back and my coffe is cold. I decided to buy this cup and I do not regret it. I can come back an hout later and my coffe is just as hot as the first sip. I nolonger am throwing out 1/2 cup of coffee. Loved it so much bought one for my Sister - she loves it jst as much!!

The mug is a nice design and weighs about the same as a regular coffee mug. Coffee does stay hot but if you dont pick up the mug for 2 hours it will shut off. Overall its a great product.

My wife loves to sit and have coffee before work but I’m constantly going downstairs to reheat but not with this mug . It’s incredible how it keeps her coffee a 140 degrees for so long and I ordered a cover which makes it last even longer . She loves her cup !!

I was initially amazed, and embarrassed, that I spent this much for coffee mugs. But after using them daily we are hooked. At breakfast, even with delays while studying the newspaper or interrupted by a phone call, we can pick up our mugs and the coffee is still the correct temperature. Luxury? Sure. Cheaper to just take a glass mug to the microwave? Sure. But this is so much better! (By the way, 30 seconds in a microwave changes the flavor of coffee by extracting more chemicals from the "fines" which get through the filter)

Had a few issues getting setup with the app but once that was settled it works great and keeps coffee hot. Very expensive.

Love the Ember! My coffee stays at my desired temperature the whole day! It is a little pricey but I think well worth it. I wish more colors were available besides black and white.

The coffee cup is a neat concept. Is it worth $129? Probably not but it does keep my coffee hot. Saying the battery lasts 80 minutes is very optimistic. Keeping my coffee at 140 degrees give me about 30 minutes before the red light comes on and it no longer warms my coffee and I have to put it back on the charger. Finally, you need to download the app to be able to adjust the temperature. I would prefer a "dumb" version where I could adjust the temperature on the cup itself.

I got this for my wife for Christmas. She absolutely loves it! I’m not a big coffee drinker like her but tried hers out. You don’t realize how good a coffee is when it’s the perfect temperature though out the cup. I’ve since had to buy my own Ember mug. The wife says it was the best gift I had ever got her. Not sure how to take that seeing that it was just a coffee mug. But I know she is happy and me not so much. How am I ever gonna top this mug now?
