Customer Ratings & Reviews

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

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.

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

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.

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!

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?

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.

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

Can’t imagine my coffee life without my ember. The 14 oz really holds 12 oz (which is the largest size on my keurig).

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.

Life changing to all of us who pour a cup of coffee, get busy, and before we know it, it’s lukewarm….. needs reheating and never seems fresh!! Keeps it perfect in temperature and freshness for that slow drinker! THE answer to fresh cup of coffee.

I bought a set for parents for Christmas. They live their coffee hot! I knew when they gave glowing reviews I needed a pair for my husband and myself. They did not disappoint. Just have to re train my brain that I don’t have to worry my coffee is getting cold run for when I get sidetracked on something and set it down. I would dump out so much cold coffee in the past but not any longer!

This a cool mug! Your beverage stays hot while in the cup and doesn't have to be on its charger! This cup will keep your drink at a steady temp for well over an hour possibly two depending on how you program it. Which is done from an app.

The cup does what it say it will do - keep your drink at your desired temperature. Over time, this period will shorten ~ 1 yr. When you try to contact customer support - the crickets come out and the stars come up. I have tried 3 times and no response. Just be aware of this if you purchase this product.

Perfect gift for the coffee drinker in your life. Easy setup for my mother who’s in her late 60’s. Doesn’t matter if it’s coffee or tea, a one time setting in the app and a long battery life make this a no brainer.

Amazing I got this for my husband in Xmas he love how his coffee is always warm

Keeps the coffee at desired temp until the last sip. Easy to setup and use. Battery life is as advertised. That said, using the included charger as a coaster virtually eliminates any concern you may have about thay.

Outstanding! Set your desired temp on the app & it'll keep it there for at least 3 hours ... and it looks great. Wifey uses it every morning & loves it.
