Customer Ratings & Reviews

My husband and I both have one. Mine is three years old now and his is one year old and they still work great and love them! I can sip on my coffee and it stays warm for almost 2 hours.

I've been using this mug for nearly a month now, and I can honestly say it is the greatest splurge I've ever allowed myself! It will keep my coffee piping hot for about an hour and a half away from the charger. I keep the charger near where I sit "most" of the time for my coffee time, and using the charger as a coaster, it will keep it hot as long as it's there. Using the app will allow you to choose the perfect temperature preferred. I believe 140 F is the max, but I've found 135 to be my sweet zone. If you use creamer, I highly suggest spending a bit more for the 14 oz option! I make 10 oz of coffee with my Keurig and with the cream added, 14 oz is the perfect size. I absolutely LOVE this mug!

Mother's Day replacement for white Ember that bit the dust after two years of HEAVY USE. Wife LOVES LOVES LOVES her Ember and wouldn't drink coffee any other way. Blue Ember on sale for a price I've never seen before. Easy pickup and perfect for wife for Mother's Day.

If you ever need to complicate a cup of coffee, get one of these. The cup itself is great. Very sturdy…if not heavy. Keeps coffee warm…when it works. Most reviews on other sites fault this to the app, which is glitchy, at best. When I get annoyed, I revert back to my little coffee hotplate(which only cost $20 and works every time I turn it on), or the microwave…and you can’t use the Ember on/in either.

This is my third cup once you have one it’s hard to do without it.the first one lasted about a year and a half the second one was new and didn’t perform as well as the first one so I took it back. The one I have now works so well the coffee burns your mouth. Great cup

On sale completely worth it. Easy to use with app, always keeping coffee the perfect temp. The color is really nice too.

This is a very cool piece of technology. If you can wrap your head around a $130 coffee mug this does a great job keeping your coffee as warm or piping hot as you want it to be. I do notice that the battery life after being removed from the charge pad at a full charge does not last more than a couple of hours, so the best way to use this is to use it constantly with the pad to ensure it stays on. The mug does not insulate the coffee any more than a normal mug once the heating element is turned off. Overall, worth it if you can keep it on your desk and it will keep coffee hot all day. Otherwise, you may be better served with an insulated travel mug like a Yeti or some brand of that sort.

Amazing cup that allows me to enjoy my coffee down to the last sip!

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.

Sleek and beautiful! Works great to keep your beverage at the drinking temperature you prefer. Very easy to use.

This is a great mug for the all day coffee drinker. The battery life is not great so make sure you leave the coaster style charger nearby. Very high quality and easy to clean.

Every sip is like the first, fresh, warm and freaking exhilarating. This cup is amazing. It truly provides "the perfect sip" every time. Only problem is the battery goes dead relatively quickly... approx 90-120 minutes. I'm a 2-3 cup guy. The first 1-2 cups go down in the first two hours I'm up. Then I kind of slowly drink the 2nd or 3rd cup until about 10:00 -11:00 am.

I really enjoy that the mug keeps my coffee hot for nearly the entire length of tha battery life. The app was easy to pair with my phone and i love the ability to control the settings from the phone.

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.

Docked a star for the price, but if you're willing to spend the money, this mug is amazing! Nothing like having hot coffee at your desired temp for hours if you choose (by using the charger as a base). Using silicone spoons to stir due to the endless number of peeling reviews out there, but no issues so far

My Ember mug stopped charging and working after about 12 months. Luckily, I had Total Best Buy Protection, which replaced the product. The only surprise was a $29 deductible, I didn’t realize that was part of the plan. In hindsight, I might’ve tried the manufacturer’s warranty first, since that would’ve likely been free. Still, the replacement process at Best Buy was quick and hassle-free, and paying $29 was much better than buying a new mug at full price.

Love the size, color and style. Keep liquids hot all day.

Best Christmas gift to give anybody. I even have a temperature now I want my coffee now it’s 129 degrees lol. I love this

My wife loved it, her coffee at the right temperature and stays warm from the first sip. Made of good material, great look and easy to clean it. Noticed there were several options in colors and sizes. It’s the kind of gift that will be used and not put aside. I don’t know if it can be engraved, which would be great.

This is my 3rd mug in about 6 years. I use them heavily so the battery starts to wear out after about 2 years. I've never had any problems with the app, although once I sync and set my preferences, I never use the app again. I don't understand why you would want or need to. I have found the Ember mugs to be exceptionally reliable and have recommended to many family and friends.
