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?

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!

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.

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!

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.

Amazing product, coffee always keep temperature. Great quality and size.

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.

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

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.

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.

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.

The keeps drink at a consistent 135 degrees for about eight hours (which is my work day). I like having my coffee warm/hot all day. You do need to charge it every day, so make sure to place the charger somewhere accessible.

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

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!

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
