Customer Ratings & Reviews

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

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

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.

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 cup, bought it for my wife she uses it everyday

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

Awesome coffee warmer mug. My wife love it because she takes to long to drink coffee

Very cool item if you like to keep your coffee hot,

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.

Great product and a great Christmas gift or any Coffee or tea drinker. I wouldn't want to give this up now that I am used to hot coffee!

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.

This is a good idea, but too convoluted. You need to connect it to wifi, app and outlet.

Great product, excellent user interface, class looking! Only thing is, a little too small for practical use. Ended up returning to get the 14 oz.

Very good rechargeable mug with temperature selection- works very very well! Charges in about 2 hours from dead, and keeps your beverages at the exact temperature you select when you link it to the APP.

Very easy to setup and use. Great for those who work at a desk and want to keep their drink at a desired temperature.

It’s a great mug.. everything good. The look .. . just size is a little small .. for the price ..

I have always loved hot coffee and continually putting it in the microwave was just annoying and wrong. I received this mug as a gift and will never drink from a regular mug again! I set it to my degree of warmth and it STAYS hot to the very last sip. And I can carry it wherever I go inside or outside. Absolute genius product! I would advise getting the 14 oz size to leave room for creamer and less spillage.

Sometimes the app won't recognize the mug- have to go thru the pairing process again but, it does what it says it will do! I tend to forget my tea/coffee while working but now with this mug, that's an issue! (First world problems, amirite?)

Great mug, works amazingly with the app to keep exactly the right temperature! Feels good and isn’t too heavy.
