Customer Ratings & Reviews

It definitely works as advertised: your coffee stays hot until your last sip. However, it does come with a price tag just over $100. That being said, it's a splurge I do recommend if youre a big coffee or hot tea drinker - its so worth it if you are.

Expensive, but it does exactly what it promises. I was able to buy mine in the BB sale, despite wanting one for months just couldn't justify full price. Super easy to set up and the phone app lets you monitor progress and status. Value for money - depends on your point of view, but keeping your hot drink hot - brilliant!!!

It is the best at keeping your coffee hot without have a lid. Works great. It’s expensive but after using it on a cold morning it’s worth it

I bought this for my wife 2 months ago. She drinks her coffee rather slow and it always got cold before. Now using the Ember Mug, she easily controls the coffee temperature via her iPhone. Now it never gets cold! She only uses it once a day (morning), so she has never ran out of battery life while drinking. I would recommend the large mug, she usually makes a cappuccino with 2 shots in it and it’s barely big enough. I would have regretted getting the small one.

I received this item as a gift. It has changed the way I enjoy coffee each day. I don't know if I'll ever be able to use another mug again. It works perfectly at keeping my coffee at just the right temperature. I have found the App to be very helpful and easy to use in setting how hot I would like my coffee to stay at. This mug even heats my coffee up after I've added cream! I can't say enough about how happy I am with my purchase. I am now working to convince everyone in my office to get one too!! It's a luxury you will enjoy!

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.

Absolutely awesome to keep at the desk. Keeps temperature exactly how i like it. The battery is nice for not placing it directly on the base all the time but nothing else - runs out in 40 minutes or less. Bluetooth connection is iffy at best, but i rarely change settings. Wish it would have the controls on the mug itself.

The Ember mug works well for tea, and there is a setting for green tea, which is what I normally drink in the morning. The mug keeps the tea at the temperature that I prefer all day. Without the charging base, the battery goes out in about an hour, so I keep the base plugged in and the mug keeps the charge all day. One negative is my Android phone does not keep the blue tooth connection.

Recently purchased. Battery might last 15 min on the pre-set temp. I really am not interested in putting the ap on my phone. Registerd the mug and put in a support ticket within 24 hrs of receiving this. Yes i did fully charge it. While it works... it is awesome. But frankly the coffee doesn't cool down much in 15min anyway. It has been a few weeks. No response from customer service at ember. I think i might still be in the return window... maybe not. I really liked the coffee staying hot, but a 15 min window and has to get back on the charger isn't worth it to me. I wish it did work for a longer time frame... support is nonexistent from ember.

Great product for the wife. She loves it so much. Great gift. It’s cool how you have control and options.

Easy to use, sleek design and keeps liquids at perfect temp

Overall a decent product if you can keep the mug charged. If the mug is removed from the charging coaster, it will only last around one hour or maybe a little less than two. I personally will not purchase a second Ember mug and will wait for the next generation which hopefully will have a longer battery life. Otherwise, the mug is easy to clean, offers good size for tea or coffee, andis a pretty product.

[Employee of bestbuy] 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.

Decent cup. Works as advertised. Battery depletes fast when in use however.

I’ve read about the Ember mug for a while now. It went on sale and I thought I would try it out! I love it!!! Bought one for my wife as well! I get to enjoy my coffee while it stays hot the entire time. No more warming my coffee in the microwave. The app is great too. Tells me the temperature and how much the battery is charged. I recommend it!!!

Awesome addition for a coffeeholic. Great temperature controls and nice ergonomic design.

The mug itself is great and is a game changer for people who take their time enjoying a cup of coffee and who sometimes set that cup down and forget about it until it’s too cold. I’m sure building this isn’t cheap but the fact that I waited for it to go on sale, used a gift card for part of the cost and it STILL was too expensive is a huge disappointment!

If you ever need to complicate a cup of coffee, get one of these. The cup itself is great. Very sturdy…if not heavy. Keeps coffee warm…when it works. Most reviews on other sites fault this to the app, which is glitchy, at best. When I get annoyed, I revert back to my little coffee hotplate(which only cost $20 and works every time I turn it on), or the microwave…and you can’t use the Ember on/in either.

Okay was it a splurge? Yes! But honestly the amount of coffee I was wasting makes this thing worth every penny. I can walk away take a call or jump on a zoom and my coffee is still piping hot when I return. Love that I can adjust the temp for tea or hot cocoa if I want it slightly warm

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.
