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

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.

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.

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

Works as advertised. This is my favorite cup and I use it everyday. It keeps my drinks hot for most of the day. I would recommend it to everyone that likes hot drinks

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

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.

Love that this keeps your beverage hot. The charge doesn’t last as long as I would like however it works well. If I was to buy again I would buy a larger size

Great cup, bought it for my wife she uses it everyday

Very cool item if you like to keep your coffee 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.

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?)

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.

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