Customer Ratings & Reviews

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!!

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.

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!

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.

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.

I was feeling ridiculous about buying a temperature controlled mug; turns out it was just what I wanted.

Love this one of the best invention ever made use mine every nite

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 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.

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. 

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.

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

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.

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

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.

Love this mug. For those that like a hot cup of coffee or tea with out constantly heatingbin the microwave this cup is gor. I truly do not know how i have lived with out it. Best buy customer service is 100% awesome Get it you will love it.

Works great and very easy to use. Wish battery wouls last longer.

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

Ok so a lot of reciews of these come from people wirh unrealistic expectations. It does everything that it is advertised to do. If you want something warm 2+ hours in great condition after you make it? Put it in the mug, and leave it on the charger and you have hot perfect beverage almost forever.

I Purchased this item because I’m on zoom all day and drink a lot of coffee. I would make a carafe and microwave each mug full to make it hot before drinking- reheating often if I didn’t drink it fast enough and it got cold. I thought this mug would be the PERFECT solution. Here’s why it wasn’t: 1- I always started with hot coffee (pour over coffee) brewed directly into the cup. Although it kept the coffee at the desired temperature, the mug lasted an average of 45-50 minutes when it was advertised to last about 2 hrs. My average meeting is 90 minutes. 2-the mug took too long to recharge, so I took to keep it in the base (plugged in) whenever I wasn’t drinking. Even though I took sips often, it would still go into ‘sleep’ mode, the coffee would get cold and I’d have to restart the mug again and wait several minutes for it to get hot. 3- sometimes it wouldn’t restart… and I’d have to exit zoom to look at the app, which would show “empty” even though the cup was more than 1/2 full. So I guess it’s not good for continuous use. It did these things so often, I returned it. So I'm back to nuking my coffee when it gets cold. It’s a hassle but it works… and it doesn’t cost $120!
