Customer Ratings & Reviews

This cup is not for everybody. My wife likes her coffee hot and she is very happy with this product. It does require daily charging, so it takes some effort. If your priority is hot coffee, this is your product.

I love my Ember mug, but there are a few things you need to know. First, it has difficulties pairing with some phones. Check their website if you have any problems. Second, once your mug is set to a certain temperature it will keep that setting until you change it. You don't need to pair it with your phone every time you use it. When you turn it on it will go to the last temperature set. And finally, the application is okay, but I have never been able to install any updates. It goes through the process, but fails and disconnects from the application. The only thing I do is push the update notifications away and I just keep using the default application. It works just fine without updating the application and it's not a problem at all. It is nice to have a hot cup of coffee at your fingertips especially during the colder weather. You can enjoy it at your leisure and every sip is just as hot as the first. I would recommend this to people who who hate warming up their coffee over and over again because it gets cold. Enjoy!

Want to preface this by saying this isn’t paid: Everything is amazingly engineered. Amazing mouthfeel, the handle is super ergonomic, diameter of the mug is perfect to hold. Great texture. Thought the tech mug thing would make it super bulky but I was totally wrong, only as bulky as any other mug. Comfortably heavy, overall elegant feel, and of course performs the task it’s designed for well, the app is great and temperature choice is so cool. Was a bit skeptical of the price but I often leave hot drinks unfinished, bought it and it exceeded every expectation and was for sure worth the money. Buy it.

Works great - keeps drinks just the right temperature. Battery life could be longer, but that’s a minor quibble. Easy to clean. Setting up the app was simple.

I bought two of these as a gift and they absolutely loved it. It was super easy to set up and keeps your drink the perfect temperature. Would recommend!

I'm the type of person I have to experience and see something for myself. I'm a believer! This mug does everything it's suppose to do. I treated myself to this as a Christmas gift and I'm very happy with my purchase. I have taken advantage of the sales around this time of year and I'm have purchase 3 different colors. It's a winner in my eyes!

A little hard to set up and figure out the lights. But very nice quality and keeps your hot drink at the set temp.

Wife loves the mug. She likes it on the hottest setting, so only stays hot for about an hour. OK for the first couple cups. Wondering if she can get a second charging tray

My husband has been wanting this mug for the longest time, but couldn’t justify buying it for himself. We recently had a baby and after I took my maternity leave, he took his paternity leave and all parents know — you get used to drinking you coffee like warm after a certain point. I got this for him so that he could continue to enjoy drinking hot coffee. He used it every day and loves it! Worth every penny, might have to get one for myself now.

Love the ember. Beautiful color and love having coffee the perfect temperature for a long period of time.

Takes over a half an hour to fully charge. However, a partial charge will do for a quick cup of coffer. It doesn't hold a charge. Fully charged it at night and had to recharge it again the next morning. Could access the app to regulate the temperature setting. Factory setting however is ok.

I purchased this 14oz cup expecting it to hold 12oz of coffee plus 2 packs of sweetener and 1 tbsp of creamer that I drink daily. It doesn't hold 12oz although it is supposed to hold 14oz. If you need a cup that can hold 8 -10 oz then this 14oz capacity cup is the one you should buy. I can only imagine how disappointed buyers who have purchased the smaller size cups are. It gets 3 stars because it does keep your beverage warm (not hot).

The Ember Mug is a level up for those who like a hot or warm beverage and like to linger over it! No more cooled off coffee before I get to the end of my reading. No more scorching test sips! The app will notify your phone or watch when the right temperature has been reached, so you can make your coffee or tea and get settled without losing your perfect accompaniment to your morning or afternoon activity. Easy to wash, not too heavy to hold or pick up, and the handle is comfortable on the fingers. This is a really great addition to my kitchen.

Works great. I love it. My coffee stays nice and hot in the morning!

I love this cup! I waited to buy one because it is definitely a splurge, but to have hot coffee throughout the morning without constantly warming it up in the microwave is huge to me. I can sit on the back porch or work at my desk and savor my piping hot coffee as long as I like. What a treat!

For me, this mug dies exactly what ghe advertise. I have not had any of the app issues people are stating in the reviews. I do have the apple phone and it connects for me everyday without issue. The temp does adjust to how i set it.. keeps it hot. We did have one cup flake a bit but ember replaced it without any issues and so far this kne is not flaking. I have purchsed about 5 of these for family and friends and they are not having any issues.

I received this as a gift. I loved it when I first got it. I've had this for a few months now. I use it everyday. It cannot keep my beverage hot for more than 30 minutes. I have had multiple connectivity issues with current bluetooth. The entire website is mainly about troubleshooting connectivity. The battery no longer holds a charge. It has to sit on the dish full time so that it can heat something up. This is a ridiculous waste of money and is probably a few generations behind what it should be. Other than that the build of the mug itself is amazing. You just can't put it in your dishwasher or submerge it underwater and it has to be hand washed everyday. I would not have paid $140 for this. What a joke. Every time I try to upload a picture of this failed mug the website is telling me unsuccessful. How hard is it to auto upload a photo BB?

Works perfectly, lots of fun. PhD student loves it.

this is my favorite thing now! I was the kind of person that heated up my coffee or tea 10 times before finishing it. those days are over. this thing works perfectly and I am obsessed with it now! if you like hot coffee or tea just get it don't even think twice! this only comes in second on my best invention ever list because my Bose sleep buds are #1- the only way I can sleep w a snoring partner.

My favorite coffee/tea cup I’ve ever had. It steeps tea & keeps any drink as warm as you want it. Plus I’m not having to wash a ton of dishes anymore because this is literally the ONLY CUP I USE NOW!! Best invention ever and keeps my coffee tasting perfect with each sip. Thank you Ember.
