Customer Ratings & Reviews

Changed the way I caffeinate. Used to keep topping off my drink to keep warmth, have now cut down to about 2 cups a day since drink stays warm until the end. Set in coaster charge at end of day and it's good to go always.

I bought this mug for my boyfriend for Christmas and I use it just as much as he does. It’s perfect for the colder months. Definitely keeps my beverages warm and get this, if my coffee has been in the French press for longer it reheats the coffee as well. Definitely buy it!

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

Best Father's Day gift I've ever received! My wife has gotten me gifts such as VR headsets but this thing has been my best gift! I can set the temperature to exactly what I like and my coffee/tea stays at that temperature all the time!

The app is extremely user friendly (way better than other competiters), easily control temps with the click of a button. Only downside is you may have to clean the base if you are messy like me. Luckily charging base is super easy to clean. Love the blue color. HIGHLY RECOMMEND!!

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

I really like this mug and use it every day. It's nice that your coffee stays hot. I'd give it 5 stars, but even at $50 off, it's really expensive. I'm sure that with all the technology built into it, it's worth it, but it's still an extravagance.

nice color and works well. keeps hot coffee hot. only downside is the battery is not as long as the 10oz version.

This is great. I used to drink my coffee fast. Or I’d get distracted and have cold coffee, Now I’m not in a rush to drink it, and if I get distracted for a bit, it’s still warm for me!

This is a nice quality item, looks good, feels good, works good. My first one still going strong after a little over two years. On high the battery lasts 30+ minutes. On the charging saucer it maintains heat all day. Not sure if the battery is replaceable.

This is now the only mug my wife uses. It is simple easy to set up and then works like a charm. Keeps temperature at the prefect temperature (adjustable via app). High quality.

Excellent quality product & on time delivery. The coffee is hot for as long as I need to continue my work & sip when i need.

I never knew I liked my coffee consistently hot until I had this mug. Now when I’m not using it, I noticed the temperature declining without it. I absolutely love it! Super convenient. Have bought a second one for my office. 

Excellent product. My second ember product that I absolutely lovez

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

I have owned 5 of these mugs and they are great for about the first year. A couple of them didnt last that long and I had to submit a warranty claim. Ember was good about the replacements but they have also deteriorated quickly. We do use them daily.

I purchase this for my coffee-drinking girlfriend. She is a slow coffee drinker and has to reheat her coffee in the microwave several times each morning. I thought this would be the perfect gift, and she loved it. It works exactly as advertised. The cup stays warm and there is no more use of the microwave for this task.

This is a must for anyone who microwaves their coffee 2-3 times before they finish it. It’s also a perfect gift because it’s one of those things that you wouldn’t buy for yourself, but you would love to own. I also feel like a baller whenever anyone asks me about it at work.

I love this coffee mug. It keeps my coffee the perfect temperature throughout the day. I bring my coffee to work in a Contigo and it does a great job keeping my coffee hot until about lunch. When I hit my afternoon circadian low I put my coffee in my Ember mug. Perfect temperature coffee in the afternoon. The only down side is the battery only lasts about 30 min. I leave it in the charger until it reaches temperature and this helps the battery last longer.

LOVE Love love it. I am so glad to have an Ember, especially the 14oz. I only wish they made a 16oz version.
