Customer Ratings & Reviews

Got this for my wife as a mother's day gift. She has a habit of leaving lukewarm tea all over the house. She loves it and it prevents her from nuking her tea in the microwave every 30 minutes.

I cant finally come back to my coffee after working and its still hot. The best part is that I can set the temp I want with my phone ahead of time to make sure I get the hot coffee I am expecting.

Bought for my mothers birthday and she loves it. Now she can work from home and have hot coffee for hours instead of it cooling off within 30 mins of being made. Easy to charge, perfect size.

I adore hot beverages (coffee, latte’s, expresso, teas, coco...) but I don’t like that they generally don’t keep their heat for very long. My mom “especially” doesn’t like anything that’s not very hot! She makes a new cup of coffee, and before even drinking it, puts it the microwave oven to heat it even more. I bought one of these mugs awhile ago to see if it was a solid item. Found out that it was, even better they came out with a second generation version which stays hot even longer! I picked one up for my mom and while hesitant to accept it, truly adores it! As a side note, it’s has a great software addition (no extra cost) that allows you to select a specific temperature and manage its power usage! My heartfelt recommendation is to try this out... if you don’t like it, no problem as Best Buy has a great return policy. I’m confident that like me you’ll adore it. Happy shopping...

This was a present for my husband. He like it very much as it keeps his coffee hot throughout even a long meal. It’s convenient and we even take it to restaurants to be guaranteed that the beverage stays hot. However, it’s quite costly and it’s strange that different colors have different, often higher, prices.

app is really well done, mug warms up super fast. only con is sometimes is has connectivity issues

Nice cup, keeps drinks hot. You control temp through an app on your phone, which I really do not like. Just like the heat plate on your coffee pot. Don't recommend letting it run too long. Also do not think it actually holds 14 oz. More like 10.

Love the cup, not the battery life. Unless I keep on charging plate doesn’t last through couple cups on Sunday mornings cooking breakfast and reading the paper.

Holy cow, I should not love this mug as much as I do, but I do. It's a total luxury to be able to set your coffee temperature down to the degree and then have it there for more than an hour. I use it every day, and despite the lofty price tag, I have been tempted to buy a second (one for work, one for home). I haven't gone there yet. My only small gripe is that the mug needs resetting once in a while, and the only way to figure out when that is is when you take a sip and find that the coffee is cold (i.e., the mug failed in its one job of keeping your coffee at the right temperature). In that case, you have to go through the typical bluetooth nightmare of re-pairing the mug. I suppose this is a complaint about bluetooth and not the mug, but still, it impacts the experience slightly. But overall, I totally love this mug and what it does. p.s. I've tried one other heating mug. That one worked by having a wireless pad that heads the mug from beneath. It was not nearly as functional as the ember.

One word. Perfect. No more cold coffee. Take your time and enjoy without fear that your coffee gets cold.

We originally went for the less expensive 10oz, but don't, it's too small. The 14oz is just about right. Once everything is synced up with your phone this little guy works like a champ. Literally will stay at the exact temperature you set it up. It will increase the temperature up to a higher temp if need be. Exceeded my expectations.

Amazing mug. It’s great to have a hot beverage next to me without need to microwave it after sitting for a while. I like that I can set the temperature to what I like and it maintains it for me. Overall, it’s a great mug but a bit pricey.

Gave the Ember-Temperature Control Smart Mug-14 oz to my son for a birthday gift. He loves that it keeps his coffee at just the right temperature, due to covid he's working from home and he keeps his house pretty cold in the winter. The Mug makes a perfect gift for a techy coffee aficionado.

I bought this as a birthday present for my adult son. He is a big tea drinker but always lets his tea go cold before he finishes it. He is absolutely thrilled with this cup, which keeps his tea at the perfect temperature until it’s gone!

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

Love it. Easy to keep clean and the dark color doesn't show stains.

Excellent - works as expected. Keeps coffee the desired temperature for as long as I need

This is at once, one of the best and worst products I've ever had. The concept is 100%. I can't tell you how glorious it is to have the first sip of coffee be just as hot as the last sip. Brilliant! I love it so much. The mug itself is a solid 90%. It feels good in the hand. The handle is decent. The battery life is not bad, and is greatly improved by the accessory lid which is an additional fifteen bucks or so. However. The coaster is an absolute cluster of a design fail from start to finish. They break like crazy, and cannot be easily repaired. Without a coaster, you cannot charge the mug, making the entire thing useless. They do warranty it, but dime to a dollar, your coaster will break 2 weeks past the warranty period. So, in order to charge your very expensive coffee mug, you will need to lay out an extra forty bucks to buy another coaster every so often. So an expensive mug becomes a VERY expensive mug, because of this horrible design by Ember.

Everything works except the firmware update. I've worked with Ember support and completed all the normal steps like uninstalling & reinstalling the app, clearing cache & data, re-pairing the device. All that works fine. It's just the firmware update that continually fails, and Ember said this is a "Bluetooth Connectivity Problem" and are not covered under warranty. Their responses include: "Connectivity issues are not covered under our one year warranty and we can only offer troubleshooting tips. " and "If these troubleshooting recommendations do not work then there is nothing else that we can do as these issues are not covered under warranty." I asked how they determine this to be a "Bluetooth Connectivity Problem" and not a Mobile App or Firmware problem, and they simply restated their policy that states Connectivity is not covered under their warranty. I gave it a 2-star review because at the moment, the mug itself works fine. At some point, however, as their app gets updated, there's the real possibility that the normal operations, such as reading and setting the temperature, will no longer work with the mug due to the App - Firmware mismatch. This is a surprisingly poor customer service policy for an expensive coffee mug.

I purchased one mug as a Christmas gift for my partner and one for myself. We both love these mugs! The app is very easy to use. The mug is nice to hold; feels good in hand. Finally, our after-dinner tea is held at the right temperature while we watch TV. I highly recommend this product. A suggestion: by the 14 ounce size.
