Customer Ratings & Reviews

I love the Ember mugs. It keeps your coffee hot and you can control the temperature from your phone. The only problem I've had with it is that it sometimes disconnects from Bluetooth ...and can take more than one step to reconnect. Other than that; it's a great mug!

I had the smaller size, but it was too small. So, i got this bigger size. Love how seamlessly it syncs with my phone and its a perfect size.

Got this for my mom for Christmas. She is retired and takes forever to drink her coffee. The coffee warmer plate wasn't cutting it. She loves it! She would have never spent the money on herself so it may seem trivial but it's a fun splurge for the coffee drinker in your life

The Ember mug is perfectly as advertised! The coffee and tea stay warm up to 90 minutes. The app is user friendly. No more warming up cold coffee and perfect for any coffee or tea drinker!!!

Love this mug. Perfect for working from home or in the office. Keeps coffee at the perfect temperatures and the app allows you to specify drink type, ounces, and even room for cream!

Christmas gift for the wife who drinks coffee much slower than I do. She loves it, keeps coffee nice and hot. Only downside is that it takes a little while to charge, so need to have it ready and charged in the morning.

This product is definitely on the pricey end for a mug but is so worth it! This mug pairs with the ember smartphone app to keep your beverage at the perfect temperature. Before this mug my tea would always get cold before I could finish it but no longer! Definitely recommend!!!

My Mother-In-Law is still thanking me for this super amazing coffee cup!

Great mug, keep my coffee at just the right temperature for a long time. Awesome capacity.

Bought this for my partner who would microwave her coffee and tea every 5 minutes. Easy to use, good app, and shes happy. Expensive, but is perfect for the perfect person.

Great while not worked but stopped charging after a little over a month. One of the charging pins is now recessed and doesn't contact the mug. Reached out to Ember, but their support is terrible. It has been nearly two weeks and I haven't received a response. Now I am afraid that the battery will be damaged from sitting in a discharged state for too long.

No more lukewarm coffee when im busy, this mug keeps it deliciously just the right temp! To keep the mug in top condition, I do use a silicone spoon to stir in my sweetener and cream. I really want to enjoy this for a LONG time!

I absolutely love this mug! I don’t have to worry about my coffee getting cold after I make it. The app shows you the temperature and you can adjust it. Now I can get rid of all my other mugs!

When I first saw these, I thought that they are absurdly priced for its purpose. I have been trying to cut my caffeine intake and thought that this would help — and it did! This allowed me to lower my cups from 5+ a day to 2! All because my coffee stays hot even if I forget about it because i get busy working. The app allows you to control the mug and set to a specific temperature you like. The mug is well built but is NOT dishwasher safe. It is ceramic coated so it doesnt affect the taste of your drinks.

Keeps coffee nice and warm. I wish it had a turn-off button, though, so when liquid is very low, it doesn't cook it. I am pleased with this purchase.

It’s amazing it keeps my coffee warm when not on charging plate and does the trick just walking around can sip on nice warm cup of joe all day

I love how it keeps the drink warm but also tells you when its at your ideal temperature just in case its too hot. Let it be known that the white mug is prone to staining when drinking black/green teas

Given to me for Christmas- love it! No problems, heats up quick! No longer reheating my coffee several times! Love the blue! So unique!

So I love that this cup keeps my coffee hot. It's an amazing cup. Downside is the app seldom works, upside you don't need the app to keep the coffee hot, unfortunately without the app you can't customize the temp. You will end up with the programmed temp.

It certainly keeps hot drinks warm, but you have to experiment with choosing the right temperature with the free app to make sure liquids are not so hot they burn. The cup construction is very solid.
