Customer Ratings & Reviews

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 absolutely love this Ember Mug. It keeps my coffee at the perfect temperature for hours, which is a game-changer for busy mornings or when I’m working from home. The app is easy to use, and the design is sleek and modern. Battery life is solid for my needs. I usually get through a full morning without recharging. It’s definitely on the pricier side, but if you’re someone who hates reheating coffee, it’s totally worth it.

The Ember Temperature Control Smart Mug² in Black has quickly become my go-to companion for enjoying the perfect cup of hot beverage. Acquired from Best Buy, this smart mug adds a touch of innovation to my daily routine. The 14 oz capacity is ideal for my favorite drinks, and the temperature control feature ensures that my coffee or tea stays at the perfect warmth throughout my busy day. The sleek black design not only looks sophisticated but also fits seamlessly into any setting. Kudos to Best Buy for introducing me to the Ember Smart Mug², a game-changer that elevates my coffee and tea experience, making every sip a delightful moment of precision and enjoyment.

Awesome mug! I’m in meetings the majority of days, which tends to mean cold coffee. Not anymore! I purchased another charger for my desk which keeps my coffee hot all day! Without the charger I was getting roughly 3 hours of hot coffee at 120 degrees. If you prefer surface of the sun hot coffee, your experience will likely be a shorter amount of time.

Bought this mug for my wife who is a tea enthusiast and she loves it. Easy to use and does a great job with keeping the tea up to temp. Cool product!

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.

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.

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.

I can only say, if you want your coffee to remain at 135-degrees (or whatever you like) then this is a must have. The battery life lasts for quite some time. 14oz is just enough to keep you happy... until the next cup. Keep in mind you can't put this in the dishwasher. The price is a little high but it works well. It is made well and very durable. I did drop it while washing it and it withstood the drop from the countertop height to the floor. Continues to work fine.

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.

OK, so this review is for the white one because I bought both colors. I was very happy with the mug's performance. It really is a different way of thinking and you get used to the idea that if you're called away, you can come back to a hot cup of java even after half an hour or so. I normally enjoy two cups of coffee every day. That's just my habit. I've had the cups for 9 months and have noticed only a slight reduction in the total time.that it'll keep the contents hot. All is well there. It sits on the charger pretty much all the time except when in use; maybe there's a better way to treat the battery :) . I had occasion to write to Ember directly and let them know that the finish on the bottom of the white cup had worn through to metal (steel) and that the cup, inspire of my pretty fastidious cleaning regemin, had stained badly. I think I would be a totally different reviewer here had it not been for Ember's response. The company stood behind their product, did not question my care and use of the mug and offered a replacement within 48hrs of my initial email. . I am impressed with the product overall, it's a cool invention and it works well. I was totally impressed with Ember's customer satisfaction effort and because of that, I can wholeheartedly recommend the product. Looks like I'll be sending a couple out as Christmas gifts this year too :)

I kept my eye on this mug for a while, and was so sick and tired of my coffee going cold at work, that I finally just went for it! I absolutely love it! Setting your preferences ( multiple can be set; for example, one temp for coffee, another temp for tea, etc) on the Ember app is super easy. After set up, just pour it up! Easy to clean, not flimsy at all, the coaster has a nice extra long power cord, it literally keeps every last drop of your drink at the desired temp! Only con is that this is not truly 14 oz. I haven't figured out the exact measurement, but using the 12 oz setting on my Keurig created a mess

This mug does everything that I wanted to do. Keeps my coffee at the exact temperature I want while still being able to drink from an open ceramic mug. It is beautiful and easy to use!

I have a collection of mugs that i dont even use anymore since i got this mug. I usually boil water and pour it in since i use instant coffee, and then just wait a little but until it comes down to my favorite temp. So far, its been great, 4 months in and I’m loving it. I will say i was concerned to see scratch marks at the base, I may have used abrasive sponge one day, but for everyone talking about the ceramic coating coming off of the base, that is covered by the manufacturer 1 yr warranty, so it’s hardly an issue. After my coffee, ill turn if off at the bottom and leave it on the counter in case any water was near the bottom charging area before i put it on the charger. Great mug, highly recommended.

My wife has a hybrid work schedule: 40% at home 60% in office. I got her both a 14oz mug and the travel mug. The travel mug works flawlessly in the 2-3 months we've had it. And the travel mug has touch-senesitive contols on its body so you don't have to download the app to use and adjust it. The 14oz mug, meanwhile, can only be controlled through the app (other than its power button on the bottom) and is great when it works, but for some reason has to be re-paired upon each use with the app and can at times take up to 2-3 minutes of troubleshooting before it reconnects to the phone app, (e.g. putting it into pairing mode one or a few times before it connects, or sometimes even requiring a factory reset before it pairs with the app.) Both the travel and regular mug versions are unnecesaey luxuries, but boy, do they serve their purpose and make you feel like you have a luxury product (especially the travel mug, but the regular mug too when it works.) For reference, both my wife and i have recent Samsung Galaxy S-series Android phones, so you may or may not have have the same experiences with these products and your phones connecting as we did if you use different devices with the Ember app.

Perfect size, and perfect length of keeping my coffee warm (I’m a slow coffee drinker). Super easy to use, and the app is a bonus. You can change the temperature of the mug, and customize the light color at the bottom that lets you know it’s fully charged.

I was looking at this for a while and only pulled the trigger once I had enough certificates to justify the purchase. The mug DOES warm up coffee and keeps it warm which is great. But this product is not worth it's retail price. First, the battery does not last long - not a big problem for me as I keep the charging plate on my desk and use it as a coaster. Second, for a fraction of the cost, you can get an insulated tumbler that will keep your coffee warm. I think this is a good product but only recommend if you have reward certificates to use when this goes on sale.

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.

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! ☕✨
