Customer Ratings & Reviews

I have mixed opinion on this product. It does work as advertised but there are limitations on its practical use. Battery life is not great - it generally lasts for about 2 hours, it must be handwashed each time, and lastly if I am using it for a hot drink for example hot coco that I use a microwave for I can't use this mug, so I am making it in one utensil and then transferring it here to be able to use it. Also you have to use the app to be able to set the temp settings.

I’ve had this mug for about a year now, and honestly, I’m really happy with it. It keeps my coffee at the exact temperature I like for a long time, which is great because I’m always busy and forget about my drink. The design is clean, it feels well-made, and it’s been super reliable. Didn’t think I’d appreciate it this much, but it’s become one of my favorite things I use every day. Definitely worth it.

I like it this mug. Use it everyday. One thing I would point out is, the battery last for one cup. But if you’re in an office. Then it should be fine, since the base is the charger

Keeps my coffee hot for longer. This thing is amazing it can even heat a drink to a desired temperature even if the drink starts out cold. Along with the app this cup feels futuristic. One downside the battery doesn’t last very long.

While expensive, I enjoy this mug overall. I usually have one ~18oz cup of hot coffee during the day. I've always used an insulated travel mug like most folks and while that's okay, they're not easy to clean sometimes and you miss out on the aromas of your freshly brewed coffee. When I'm at home, I enjoy using a regular mug, but the downside is the coffee cools down too quickly. Enter Ember, which allows me to use a regular mug, but keep my coffee as hot as I like it for as long as I want to. There are only 2 downsides. 1) battery life is lacking. No issue when I'm working at my desk and I can keep it on the charger, but on the weekend if I'm relaxing on the couch, it doesn't last as long as I'd like to keep it hot. 2) maybe it's because it's cold right now, but condensation forms on the charger when the mug is on there. Overall, while it's a splurge I recommend it if you don't mind the high cost.

Nothing worse than your coffee going cold by 10am. It's better to ease into your caffeine intake and enjoy the flavor of your coffee throughout the day. I can keep my coffee hot until mid afternoon, but I usually finish it by noon anyway. There's no rush to chug it down! The app was a bit clunky to use at first, but I appreciate that it can detect liquid in the cup and it won't turn on the heater if it's empty. The "personalization" option is a bit silly, as the LED indicator is busy 90% of the time indicating whether the heater is active or the battery is low. You'll only see your personalized LED color if it's idle with good battery charge. Don't expect to enjoy this too far away from the charging base, however. With the heater active at 134F it won't last more than 40 minutes off the charger. The best way to use this mug is to simply use the charging base as a coaster and park it there when you're not taking a drink from it.

I love it! My coffee and tea is now always at the perfect temperature; never too hot or lukewarm, but PERFECT! If the coffee is lukewarm going into the cup, it get heat up, while extreme hot coffee cool down. A phone notification (if you set it with the apps) will let me know when it ready to drink. I tried testing it out to see how long it could last, and although, it couldn't keep my drink warm all day (there seems to be an auto-shut off, after several hours), it could keep my drink warm for a 1 to 2 hours, depending on the temperature set. You can also just leave it on the charging tray for longer, if need. I also tried using it for soup and found that thicker soup seems to not work quite well with the temperature setting, the bottom is always a bit hotter than the top. Especially, if you put lukewarm soup in hoping to heat it up. Not quite good. But hot soup can stay warm longer, which is nice, when you have your soup last like me. Coffee and tea at perfect temperature--I love it!

The Ember Temperature Control Smart Mug is a game-changer for hot beverage enthusiasts. Its sleek design and 14 oz capacity make it a stylish and practical addition to your daily routine. The temperature control feature ensures your drink stays at the perfect warmth throughout, providing a consistent and enjoyable experience. The accompanying app allows for customization, letting you select your preferred temperature and receive notifications when it's reached. While the price point is higher than traditional mugs, the technology and convenience justify the investment for those who value a precisely heated beverage.

I wanted an Ember mug for years, but my budget is rather small. I found it on sale and decided to bite the bullet and buy it. It's great, but I have 2 things that sort of bug me. It will not stay connected to my Google Pixel Pro 7 which is a huge disappointment. Also, when the battery needs to be recharged, it seems to take a long time to charge. But, that's somewhat tolerable. Not staying connected to my Google Pixel phone is what really irritates me. Other than that, the mug performs as expected.

The concept is great. But the product has issues that make you want to return it. My wife needed this cup to keep her drinks at her ideal temperature. That's great! BUT... It only connects to the app occasionally, maybe 40% of the time. With her Android phone it worked at first. Then shortly afterwards it asked to update, which she did. That was the beginning of the end. The second generation cup can be a great product. Submersible... perfect. Chargeable..needs to be longer. Style... nice. Price..needs to be less!! Connectivity..terrible!!! We may be returning this if we cannot get it corrected and connected. For the price, it shouldn't be this way.

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

I recently purchased the Ember 2 coffee cup as a gift for Pastor Appreciation. He is absolutely enjoying the mug! The customizable temperature feature ensures his drink stays just the way he likes it. He was particularly impressed with the battery life, commenting on how long it lasts, which makes it even more convenient for his busy schedule. It was the perfect gift for a coffee lover.

I bought this mug for my boyfriend because before he would complain about his coffee getting cold while he was working and I figured this would be the perfect solution and he loves it. The app is amazing because it tells you the temp of the beverage so you know when it’s too hot or perfect temp!

Really really great cup! It either keeps your coffee (or whatever hot beverage you drink) the desired temp right to the last drop or warms it up to your desired temp. This is the second one I’ve purchased. (Husband was so impressed with the one I bought a couple of years ago, he wanted one.) Highly recommend. I ordered from Best Buy at an excellent price — it came quickly and packaged perfectly.

Great! Excellent quality and love the blue color. Would be even better if battery lasted a little longer.

I absolutely love my Ember Temperature Control Smart Mug²! The sleek copper design is both stylish and functional. It keeps my coffee at the perfect temperature for hours, making every sip delightful. The app integration is seamless and easy to use. It’s a game-changer for coffee lovers. Highly recommend! ⭐⭐⭐⭐⭐ Enjoy your perfectly hot beverage! ☕✨

Got the Ember Mug 2 for my mom’s birthday because she works from home and only drinks her coffee when it’s piping hot. It’s been awesome. She sets her ideal temp, and the mug keeps it there without having to reheat. The battery lasts long enough for a full morning session too. If you love hot coffee and tend to leave it sitting while working, this mug is totally worth it.

Love this heated cup, I have had it for more than a year. I have also gifted to a friend. The temperature & color control features and the application overall are ok; it is overkill since the settings therein are more of a George Floyd "set it and forget" kind of thing. Without the base, the battery last only one hot mug. I feel the cap is a must and should be included with the cup; alas, I recommend you get it with the cup. I would recommend this product.

I have wanted one of these for years and did not want to spend the money. I work from home and end up warming up my coffee multiple times a morning due to meetings. I finally pulled the plug and am so happy I did. I love the fact that it keeps my coffee the perfect temperature until I am finished, and it is also very easy to clean.

I was a little unsure about this item after reading other reviews, but I have been very pleased with this mug. Like others, I wish the battery would last longer, but after buying a lid for it, I am able to enjoy warm coffee for much longer.
