Customer Ratings & Reviews

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 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!

Perfect for keeping your coffee warm while at the office or home.

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!!

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.

Since my family got me one of these for Father's Day a couple years ago I can't use anything else. I usually drink coffer throughout the day, and I nurse it. That normally means cold coffee, but this thing is the answer to that, My only complaint is that the battery doesn't last that long (keep a charge plat near) and if you use metal spoons to stir you will damage the ceramic coating on the cup. I have gone through three of these now, but I won't live without it.

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 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.

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

So far so good gave to wife for xmas she loves it Will buy another she wants one for work now

Works great, keep my coffe hot all the time, just work great for me

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

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

Bought this for my wife..she loves it..easy to use too

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.

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 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. Keeps coffee hot for a very long time.

Great cup and keeps coffee all day. Bought as a gift for my Daughter and she uses it every day

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.
