Customer Ratings & Reviews

It does exactly what it says. It keeps beverages hot for an hour or 2 after it is off the charger.

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.

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!!!

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.

Didn’t think I would enjoy using this cup but it truly keep your coffee hot from the moment your pour your coffee to this cup until hours later

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!

It works but needs a charge constantly. Therefore i think its overpriced.

I bought for my college age daughter for Xmas. She drinks tea most days and is always up reheating. She loves this and says it works perfectly!

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.

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.

I bought my husband and Amber mug couple years ago. It was only a 10 ounce mug. No I upgraded. he loves it. No more microwaving reheated coffee.

Bought this for my wife as I’m not a coffee or tea drinker. She likes it but the battery life doesn’t last long at all. I think it’s rated at 80 minutes and that might be on a good day. She just moved the base to her desk and it pretty much stays on there all the time.

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.

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!

Controlled by my iPhone. I don't like lukewarm tea. This cup does what it says and honestly keeps my tea at 142 degrees to the last drop. I keep filling it during the day with tea from a thermos and it heats it up within a few minutes. Expensive - yes - but it's been worth every penny for me to enjoy hot tea every 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

Excellent smart mug. Works really great to keep my coffee warm at the perfect temperature at my desk. The only reason I did not give it a 5 star is because the battery life could be a little better. I did get around that by plugging in the coaster on my desk.

Love it and use it several times a day. (8am-9pm). The reason I gave it 4 stars; The app could be better, the light on the cup could be more intuitive, and battery life could be better (1.5 hrs without charging).

I have bought two of these now and they work well. If you give to someone that uses the microwave to heat their coffee hide or unplug it. They will quickly burn the circuits and no longer work.
