Customer Ratings & Reviews

Wife loves it. But it's mainly for if you drink your coffee just black with sugar. We have learned that if you have cream or half/half, it will basically cook and you will have a skim on top. Great though. Would personally get the Ember2 so you could set your own temp. This holds true and keeps it hot for around 80min.

Great mug and does the job, just wish the battery lasted a bit longer.

Ember cup is super. Keeps my coffee warm all morning. Couldn't live without it.

I love this mug! It keeps my tea at the perfect temperature all afternoon! You can control the temperature you want it set at and it handles it from there! Highly recommend!

Bought for my wife and she loves it. No more cold coffee!

Bought as a Christmas gift. My wife absolutely loves it. No more microwaving to heat up her coffee. Even after she puts some creamer in her coffee, still hot to the last drop.

This was a great purchase. I normally drink my coffee from a Yeti to keep it warm but on the weekends I enjoying drinking from a mug. Temp control is perfect!

Great buy! Keeps coffee at perfect temp, throughout drinking it!

Keeps coffee warm and is easy to clean and charge.

Once you get one of these you’ll never want to use a regular mug again. Works as advertised - great for coffee and tea!

Great mug. Works to keep coffee at 135 deg or your preference. Before I had to run to the microwave multiple times to keep my coffee hot. I like to slowly enjoy my coffee. Since Starbucks will not allow thermal mugs anymore, this replaces that and better. Enjoy your coffee 100%

Excellent buy, definitely would recommend, keeps my coffee nice and hot all day while I work, works great for any home office.

I bought this item for my wife. She absolutely loves it. She loves the shape of the cup and the fact it's not heavy considering the technology. Her favorite function is that she can control the temperature from her phone app.

Got this for my mother and she loves it. 2 out of 5 days she works for home and it does well with keeping her coffee warm while she is preoccupied with meetings and such. Thinking about biying one for myself

Whoever invented the Ember mug is a genius! It has changed my coffee-drinking life, because I love my coffee hot! This product is not a luxury for me, it's a necessity!!! The only drawback is that it is not dishwasher-proof. You also can't put in a microwave, but you don't need to because it keeps your coffee so hot.

This is exactly what i needed. I drink slow and am constantly reheating my drinks

Great mug keeps my coffee hot for hours!!!! The app is very intuitive as well!!

This was my third cup, love these cups. This was a gift and she loves it too. I will get the travel one for my vacation this summer. Never have "warm" coffee again.

I like that it keeps the liquid warm for a long time at the temperature of my choosing. It unfortunately has connectivity issues and the app needs to be reloaded to connect.

As with many smart devices, I think the mug performs its function very well but the app needs a bit of work. I appreciate the features offered by the app (multiple temperature settings, etc.), but it consistently becomes disconnected from my phone when the app "forgets" the mug's configuration. When this happens I have to press and hold the bottom button to enter bluetooth pairing mode, which is made more frustrating when the mug has already been filled with coffee. Additionally, the app has been prompting me to complete a firmware update, but stalls out near the tail end of the install and never completes. Maybe if we could complete the firmware update then the disconnection bug would be resolved, but I guess we'll never know.
