Customer Ratings & Reviews

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.

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.

These mugs are decent. They keep your drink somewhat warm for up to ~an hour and a half, even if you have it set on the charging pad. The heating element is located at the base of the cup which creates more of a temperature gradient, which is pretty noticeable if you have a full cup of coffee. If you have a milky drink like a latte in it the milk usually burns a little at the bottom leaving a fatty residue, which isn't a big deal but it isn't ideal. Ultimately I find these mugs to be overpriced and not worth it when you can get a really good thermos for a fraction of the price and it will actually keep your drink warm longer given the limited battery life of the mug. It's unclear how long the batteries on these will last. It could be that over a year or Overall, these mugs aren't quite worth the price, though I really wanted them to be.

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.

Really surprised at this Heated mug. My wife has been asking for one for a few gift occasions, and I always thought they were silly. Well I got her one for Christmas finally - and she loves it! She uses it all the time- it’s the only mug she uses at the house (still uses travel mugs). But these are so cool that I’m convinced and want one for myself. I’m going from thinking they were silly to asking for one for my birthday!!! Would expect others would be sold like me. A great gift idea as it may not be something someone would splurge on for themselves

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

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!

A truly excellent temperature control smart mug, delighted to have purchased it, works great

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.

This is the larger of the two Ember mugs and the seemingly slight difference in size is worth it. I had the smaller size for awhile and really liked it, but eventually the inside coating began wearing away. I'm hoping this one will be hardier - it seems better at early glance at least. I admit this is a frivolous item, but I really love being able to drink my coffee slowly and not get cool.

The ember mug exceeded my expectations. The mug feels high quality and looks really nice as well. It keeps my coffee just as hot as I poured it till the very last drop. It cleans up well, the app is simple and easy to use, and the charging feels futuristic. I would recommend this to anyone who hates when their drinks get cold, this is the perfect solution.

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

Got this as a gift from my husband so I would stop leaving my mug in the microwave. It is great, I love that I can set the temp I want on the app and take it with me around the house or the office. PS don’t tell my husband, sometimes I forget to put it back in the charging base and my coffee gets cold anyway lol

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

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.

Love this! The white color makes it look sleek and clean. Keeps my drink hot for hours!

[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.

[Employee of bestbuy] The Ember Mug is a great gift for anyone anyone who enjoys their drinks to be hot, and to stay that way. They provide you with a nicely-sized cup which not only comes with an app to customize & set your own temperature, but it also has built in thermal technology to keep your hands safe & store all of the heat inside.

I like the design and comfort of the handle. The flat design is the most comfortable for holding/gripping the mug.The lip is not thick also. I've had no problems with the app. Too bad the battery only lasts 1 1/2hr. before charges. The price is a bit excessive, but Im keeping it.

I bought this Blue model on sale to try before getting another as a secret Xmas present for my Daughter. It works as advertised and I am extremely happy and my Daughter says "best present ever" as she works 2nd job from home at desk for hours at a time. The initial 135 degree setting I thought was a little too hot for my taste but I have gone back to it after trying 125 degree recommended by some Coffee guides. Initial setup for the App was okay but not intuitive that you must actually follow a few extra steps even though the prompts are already saying press "here". It is best to manually sync the cup in your phone's Bluetooth first before trying to follow the App. After that go slow and let the App sync until it gives you the menu. I only used the App to change the temperature and it is not required to keep that setting. If you are going to move the cup from your Coffee Bar/Kitchen often it is best to have a 2nd charger base just to not have to walk back for a charge if you are holding a cup for long sessions in another primary room. Following guidance to not use metal spoons and non-abrasive cleaning and no issues yet with the interior coating after 4 weeks of use.
