Customer Ratings & Reviews

I like it, but wish I had bought the larger one.. it says 10iz, but 10 takes to rim, so really only holds 8 comfortably.. it does keep coffee warm - so it does its specific job..

This coffee mug is a great concept! Something that keeps the coffee or tea warm for a longer period of time using a battery. I got this for my wife and she loves it. She drinks coffee more slowly than I do so hers always went cold and she'd have to microwave the same cup at least twice. Not anymore! Cons are that it's a bit heavy and quite expensive.

This really keeps your drinks warm. So far no issues with the mug or app. The deal price was definitely worth it.

Easy to use. Keeps my coffee hot. Has been for the last year with out fail. Now definitely will buy silicone spoons for the next one becaude it now has some bad stir lines.

This mug is great to keep things warm. It doesn’t seem to hold a charge as long as it says—maybe good for two mugfuls before recharging. Also consider getting the 14 oz. The 10 oz may be a bit small, depending on how much a person usually drinks

Love this in the winter for keeping coffee, tea, and cuder warm. The app is a little glitchy amd wont always connect with my phone. That is the only reason I removed a star.

This mug is wonderful! It keeps my coffee/tea so hot for a long period of time. I do wish there was a size between this mug and the travel size mug. And, it’s a bit heavier than a normal mug. Overall, I would definitely recommend this product!

I give it four stars because number one I didn’t want to download the app. Never too it doesn’t hold that much. It’s one cup that’s it But oh, what a relief it is to have a nice warm cup of coffee .

I got one as a gift and oh wow! I love that my last sip of coffee is as hot as my first. I drank out of it every day. It lasted for years! Their customer service is TOP NOTCH. I wish every company and product were as good as this one!

I love this mug. Finally I can have my hot coffee until the last drop . This mug is very well made. The sleek minimalist design is appealing which almost reminds me of a product apple would design . The app is also easy to use to program the temperature according to how hot you like your coffee or tea.

I like having my coffee stay the same temperature to the last sip. I also purchased the lid for the cup.

the cup works great, heats up quick, and keeps accurate temperature. Build materials are premium. The app doesn't connect all the time, even though is not required, unless you want to set the temperature to a new value.

Wow!!! Just wow! every coffee drinker needs this. Amazing

My Ember mug has quickly become the only mug I use. It has the feel of a conventional mug, but the technology inside keeps my morning coffee perfectly heated to the final sip. The app was easy to install and synchronized, but honestly, once I set the mug to my desired temperature, I haven’t used it. I would recommend this mug for anyone who looks forward to their coffee every morning like me.

Great coffee mug. I bought this because I’m always getting busy at school and forget my coffee until it’s cold. There is a bit of a learning curve and the instructions aren’t great, but after a bit of trial and error I got it down. If I did it over again, I’d opt for the 14 oz. mug instead of the 10. My Keurig is set for 10 oz servings and it fills the Ember mug pretty close to the top which makes it too easy to spill if you arent super careful. All in all, I would recommend getting one, regardless of size.

Overall a nice purchase. I like the app but wish the temperature and battery life were on the same page. 145F temp is good for me, just right that it doesn’t burn. I keep the charger in my office and charge the mug overnight. In morning charge lasts 2-3 cups.

This mug has earned a spot on my work from home desk because of its set it and forget it and ease of use. The mug is on the smaller side with only 10oz but works as advertised. The max temperature the mug can maintain is 145 so if you like your drinks scalding hot this may not be the mug for you.

Easy to use , good quality exact what I needed in the mornings.

Works excellent does exactly what I was advertised and I wanted!

This is a MUST for every HOT tea/coffee drinker! It's a perfect office gift.
