Customer Ratings & Reviews

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.

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

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.

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.

I bought this as a Christmas gift for my husband. I thoroughly researched smart mugs and determined this to be the best choice. He loves it and has used it daily since.

My husband’s favorite gift of the year. Keeps and warms up to temp after adding creamer for like 90 min! No more microwave. I feel bad for our other mugs though.

Awesome product. I was a little iffy about paying $150 for it but 100% worth it. The fact that my coffee will consistently stay the same temperature is great

We bought this for my mother-in-law for Christmas. She loves it! She likes working on one cup of coffee for a while so it helps a lot keeping it warm for her.

My wife loves this mug. She set it up on her desk at home. When she left work she set the temp, by the time she got home it was nice and hot ready for tea.

Just bought my second Ember mug. Yes a little pricey but what isn’t these days. I use my mug every morning and love it. Yes i wish the battery would last 2hrs but an hout and 15 (75min) is what i get. I love mine!
