Customer Ratings & Reviews

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 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.

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 love this mug. I bought a black mug but could not see coffee in it because I drink it black. I gave the black mug to my wife and I bought this white one. I set this mug to 130 degrees, my perfect drinking temperature. I watch TV in the morning while getting ready for work and the battery life is sufficient for that. Putting a lid from my thermal mugs keeps the coffee warm for a longer period. I have a charger on my desk and it keeps my coffee warm all morning. My only con is that the charging base stopped working 13 months after I bought the mug. I have the Total membership but I have to have a tech look at the device before they will warranty it. Not a big deal. Be sure to buy the extra warranty as it covers all you BestBuy purchases.

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.

Decided to give this mug a shot as I have heard about them for awhile now. It is straight forward to use, and the app is user friendly. The battery time averaged is accurate so far in the beginning of its' life. I can get about 70-80 minutes before it is telling me I need to put it on the charger, that is at 137 degrees. Setting it hotter or cooler would extend or reduce the time. If you are someone who works from home or have this in the office, it is easy enough to have the charger on your desk and set the cup into the charger to help extend the time. Overall, a great purchase that allows consistent temperatures out of multiple cups of coffee. The best decision I made was spending the extra money to go with the 14 oz. over the 10 oz. I usually brew a 12 oz. cup from my Keurig, and if you add milk or creamer, you would have to reduce your brew cup size in order to make it work.

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

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.

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 absolutely LOVE this cup! I actually look forward to using it every morning at my office. I usually drink a couple of cups of coffee each day and usually have to heat it in the microwave a few times before I finish each cup. This cup keeps the temperature at exactly the temperature that you like. I've tried various temps and the default of 135 degrees is the best. This cup is not meant to provide hours of charge off the base, however, it did last for a 1-1/2 hour meeting before returning it to it's base for charging. It's perfect for the office because I'm up walking around and back to my desk often, so it's constantly being charged again while I'm sitting at my desk, but still stays hot while working things out in the warehouse.

Love the color and works great. The battery does die pretty quickly though, but you can leave it on the charger as a coffee stand.

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

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! ☕✨

I didn't know I needed this until I decided to get one. My sister and I share an office and have a coffee machine that we use to brew coffee, tea, cocoa, cider etc. I found the 10oz version of this at Best Buy on sale one day, and decided to get one for my office (It's irritating when my drinks get cold because I add cream/stir them/don't drink it all immediately). Was reluctant at first, and thought "Did I really just buy a smart drink mug?" Now I think to myself "Did I really just buy another two smart drink mugs on top of the one I originally bought?" Absolutely love this thing, and my sister loves hers for keeping her matcha hot. App is easy to use, setup is a breeze, and the quality feels sturdy/well-crafted.

This seems like an extravagant purchase but if you spend the extra time and money to making great coffee, this really makes a big difference in how it tastes. I didn't realize how much I didn't enjoy the last half of my morning coffee until I experienced what it's like when it's at the same temperature as my first sip. The only problem is I now find myself wanting more coffee because the end of the cup no longer puts me off. Product is well built, easy to use and is exactly as advertised.

Quality product that my husband uses everyday. He was always reheating his coffee and now he doesn’t have too.

Works well - keeps coffee from getting cold. Battery life could be longer but if you keep keep it on the charger then it’s not an issue. Price could be cheaper. App is not really useful at all.

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.
