Customer Ratings & Reviews

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

I like it. It keeps my coffee, warm and cold weather.

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)

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.

Excellent piece of technology. I use mine everyday. The battery doesn’t last too long, maybe 2-3 hrs off the charger. But does what it needs to do and satisfying at that. Works well and very simple.

Great product and love the temp control! Only wish it was a little bit bigger. 20oz maybe? Otherwise great product!

beautiful mug! Love the color. The temperature control is perfect!

Christmas present for the Wife. She has been wanting one for a pretty long time. Seen a few reviews showing that the interior coating coming off and my only guess for the reason for that is that maybe they used a frother. Anyways this only gets hand washed and it is performing like an absolute champ. Do wish that they had a 20oz that was not the tumbler though.

Serious Quality & Safety Concerns – Disappointed with Ember Mug I purchased an Ember Mug and treated it with great care, but was very disappointed to find that the interior coating began chipping and flaking off over time. This raises serious concerns for me about potential toxin exposure, as I may have unknowingly ingested harmful materials. I reached out to the company with hopes of a responsible resolution—specifically requesting a replacement mug made of stainless steel or another safer, more durable material. Instead, I was offered only $32 toward the purchase of another expensive mug that could very well chip again. This response felt inadequate and dismissive, especially given the potential health risks. TOXIN ALERT – I urge others to think twice before purchasing an Ember Mug until these issues are properly addressed. Product safety and customer health should be the top priority.

This is our fourth ember mug in our collection and we use them daily. The battery lasts a decent amount and being able to set the exact temperature really puts the icing on the cake.

Like this mug so much, I bought the travel mug and sent one as a gift. If you like your coffee to stay hot the whole time - it is great!

Love this mug. Keeps my coffee hot for hours even if I forget to drink it right away. Easy to clean.

I got this for my wife for Christmas. She absolutely loves it! I’m not a big coffee drinker like her but tried hers out. You don’t realize how good a coffee is when it’s the perfect temperature though out the cup. I’ve since had to buy my own Ember mug. The wife says it was the best gift I had ever got her. Not sure how to take that seeing that it was just a coffee mug. But I know she is happy and me not so much. How am I ever gonna top this mug now?

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!

Does the job well, just couldnt help butvthink the wuality was fantastic

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.

Love that it keeps my beverages warm. Easy to use and keep clean.

It was a great gift! Keeps everything warm and is very easy to use.

Bought this for my friend who loves coffee, she fould it very easy to use and loves how you can adjust the temp on the app

It's definitely not a necessity, and I wish it was a bit more reliable in terms of when it keeps my coffee hot and when it turns off. I'm figuring it out as I use it, and it's nice to come back after an hour or so and find my coffee nice and hot.
