One word. Perfect. No more cold coffee. Take your time and enjoy without fear that your coffee gets cold.

Love the Ember! My coffee stays at my desired temperature the whole day! It is a little pricey but I think well worth it. I wish more colors were available besides black and white.

Use every day! Keeps my coffee and tea at a perfect temperature. Great quality.

I have been using one of these terrific mugs at home for over a year. Once you have had one it is difficult to live without, hence this new one for the office. This ingenious product delivers exactly as promised keeping your tea or coffee at exactly the preselected temperature for over an hour off the base and indefinitely on the base. I thoroughly recommend it.

app is really well done, mug warms up super fast. only con is sometimes is has connectivity issues

It does what it claims to do. It keeps beverages at desired temperature.

Perfect!!! I'm not quite sure WHY we didn't purchase it sooner but it's a gem. I enjoy taking my time and sipping my coffee without the worry of it getting cold. I only wish the charge lasted a little longer.

Great deal. Keeps coffee hot, ego high aside wife’s white one.

Great gift for elders! Can be a little hot but that’s as intended, good for reheating coffee/tea and still taste great

Wonderful coffee mug keeps my coffee hot for quite some time. I like the larger capacity. Definitely prefer the dark colored mug. An excellent investment.

Had a few issues getting setup with the app but once that was settled it works great and keeps coffee hot. Very expensive.

I was initially amazed, and embarrassed, that I spent this much for coffee mugs. But after using them daily we are hooked. At breakfast, even with delays while studying the newspaper or interrupted by a phone call, we can pick up our mugs and the coffee is still the correct temperature. Luxury? Sure. Cheaper to just take a glass mug to the microwave? Sure. But this is so much better! (By the way, 30 seconds in a microwave changes the flavor of coffee by extracting more chemicals from the "fines" which get through the filter)

On sale completely worth it. Easy to use with app, always keeping coffee the perfect temp. The color is really nice too.

Keeps everything warm. Does what it says it does. It’s good for one cup, so kind of sucks to refill if you drink a lot.

I LOVE this mug. It is a wonderful product that provides and keeps my Americano hot. HOWEVER! As much as I LOVE this mug there is a huge flaw of this mug. The battery life. The purpose of this mug is to keep my coffee hot for a long period of time… but when the battery life of my mug is like an hour, it doesn’t last as long as it should. Basically you have to keep it on the charger otherwise it will die quickly and you just have a $100 mug. So in conclusion. AWESOME product that when it has battery, works amazing. It just doesn’t last long enough on a charge!

My husband and I each received an Ember mug as a gift. We weren't sure if they really worked. They do! We've been using them for over 2 years and love them! I'm a coffee drinker, but also drink tea. I'm able to set the temp that I prefer for whatever I'm drinking. We use them every day and recommend them to anyone who enjoys their coffee or tea the same temp with every drink.

Doesn't connect all the time and have to keep resetting it but when it does connect it works great.

Ember mugs are great if you enjoy hot coffee. I have a charger and extra heater so I can enjoy hot coffee for hours. Standard mugs lasts 1.5 hours.

Purchased as a gift and my friend loved it! Especially the color and as an avid tea drinker, he can't get enough of it. I did purchase this on sale so not sure if the color of the mug matters.

I love that it keeps the coffee at the perfect temperature for me. The battery won’t last more than 50 minutes off the charger, but I usually drink it with the charger nearby so that’s fine. My only ding is that the charging pins stick after a while and it struggles to maintain a connection to properly charge
