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

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 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.

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.

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.

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

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

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.

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.

Something I’ve always wanted! My coffee stays hot even when I’m not in a hurry. Stays warm and fresh.

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.

Product works well. Disappointed in the size of the cup

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.

I am in meetings all day long and this ensures that I always have a warm cup of coffee or tea close at hand.

My wife bought me this mug for Christmas. I love it! My coffee constantly stays hot.

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

This cup is absolutely amazing! Its great!! Keeps my tea warm and tasty!

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.
