Customer Ratings & Reviews

This cup is both intuitive to use and set up, and does what it says! As a busy household, many a cup of hot stuff (tea/coffee, chocolate) has been thrown out for going cold. This keeps it toasty and drinkable for hours without it going stale. Would recommend.

Perfect for a gift to someone who constantly warms coffee in the microwave.

My wife uses it almost every day. Easy to clean!!!

My wife and I always fight the temperature of our coffee in the mornings. We no longer have to do that when getting distracted with the kids and their activities. All I have to do is place it on the charger and come back hours later to a perfectly hot cup of coffee... It's so awesome! Be sure to blow out the bottom since water likes to hide in the grooves (it's waterproof but just to be sure).

love this cup, keeps coffee hot. I love the new size too.

These things are great. My wife and I each have one already. So this was a gift for my father in law. You can take your time and enjoy your coffee instead of trying to scarf it down before it gets cold. Can even enjoy it out on the deck when it’s a little chilly outside because it stays hot. I keep mine at 128

Great mug! Keeps the coffee warm. The size was great.

I received this as a holiday gift and wasn’t sure how often I would use it. Then I got my seasonal cold and it is a lifesaver! The app is great as I can track and set the exact temp of my tea. The cup knows when it’s empty and shuts off!

A welcome addition to my office. I no longer need to bring a travel mug to my desk. My coffee or tea is kept at the temperature I like. It also has a nice feel in my hand. It even has a timer for my tea. No more wasted cups of tea and coffee.

Who would possibly want, much less pay money for, an electric coffee cup? I mean, REALLY.... Well this little sucker is the niftyest, coolest appliance in your kitchen. Great quality, practical, a real joy! Recommend Ember cups Unqualifiedly.

The mug does an excellent job at keeping the coffee warm. The app is a bit finicky and needs to be updated.

I like this cup. It looks nice and funtions perfectly. But the battery just doesnt last long enough and it takes a while to charge. If youre the type if person that drinks coffee all day, maybe get a thermos. If you just have a cup if two for breakfast. It works well.

I bought this after I noticed a friend had one. I am a tea drinker (especially in the winter). This cup is great for keeping drinks warm. I like that you can adjust the temperature as you like. There are also preset temperature recommendations for specific drinks.

Iught rbis cup for my wofe and is by far the best goft i have ever given her!!!

Cool device, I like the app but a little hard to control without app. Works pretty well a little pricey if not on sale.

Cool Idea, Got this for my Wife and she loves it. Keeps her Tea warm for hours.

There's nothing quite like going back for another sip of my coffee that I made 30 minutes ago and have it still be at the perfect temperature. I've had this for about a year now and I am in love. You can't go wrong with an Ember mug or tumbler

Great experience so far. Beautiful color and design and heating system is great.

Great product. Wife uses it daily and no more cold coffee! Super easy to use.

I've always enjoyed coffee, but I don't like it too hot, and I don't like it too cold. First world problems, I know. However, my Ember cup has changed my world. I make a cup, wait until it reaches my set temperature (128), and then start sipping it. Amazingly, my coffee remains at 128 degrees from that first sip until the last one. If Maxwell House had not already used the phrase, "good to the last drop", then I would apply it to Ember, which would be more true. This thing is worth it!
