Pretty good mug. It does keep the drink at a proper drinking temperature, doesnt die too fast.

I like the cup but it is a bit on the heavy side. The concept is great and it does keep my coffee warm. The coffee comes out of my Kuerig at 156 degrees, which must be about normal but the highest setting for the cup is 145. I don’t think I get the full 90 minutes of battery life with the setting at 145. It’s a great concept, I just wish it could keep my coffee hotter.

Bought as a Christmas gift for my wife, she loves being to keep her coffee warm in the mornings. Only downside is they should include from the factory a lid for it to extend battery life and help with spills.

These are great, wife loves them. Her last one lasted several years before it wouldn't charge anymore.

Some say, $130 for a coffee cup?!!!!! I just say, YUP! and it is worth every penny! I use this cup almost every day. If you are a coffee drinker or really any hot beverage drinker, you can take your time and savor it without the worry of picking it up absentmindedly and taking a big swig of luke warm or worse, cold liquid. Your 100th sip is as hot as your first. And if you are like me, absentminded at times, when you brew your cup and forget you did so until you happen to walk by it 30min later it isn't a big deal. It was sitting there waiting for you as hot as it came out of the brewer.

Works as advertised! Two recommendations: 1 needs longer lasting battery 2 or provide extra charging plate so you can charge in multiple locations.

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

This product is amazing! I no longer have to worry about my coffee going cold even after hours of schoolwork, my coffee is as hot as when i first brewed it. I will say that the only downside is the Embers app, but to me its not that big of a deal because i can use the mug without the app.

I purchased the Ember a week ago and i absolutely love the fact that it is easy to set up and use. The product works as advertised and keeps your drinks at your desired settings. I will be buying more as Holiday gifts. Taneisha Howell

Love this so much. No longer have to reheat cold coffee. Very easy to control, a great gift for coffee/tea drinkers.

I bought this cup for my wife. She likes to take her time drinking her coffee and latte. She would usually have to microwave her cup two or three times to keep it hot. This cup does the trick! Keeps her coffee nice and hot, 145*, for hours! You can adjust the target temp to your preference but it tops out at 145. Great cup and has held up perfectly since purchase almost 6 months ago.

Never thought I'd need temperature controlled mug but it is more useful than I thought. It's great to always have a hot drink especially since my house is very drafty. Only downside is price.

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...

These mugs may seem like an extravagance - but when you experience access to hot coffee thirty minutes after you filled it.. you can't avoid a comforting smile! We bought two of them - one of them has less battery life. I doubt the battery is replacable.

Easy to use. Works great so far. I feel like it’s worth the money! Go get you one. You won’t be disappointed. The fact that you can watch it heat up to the temperature you set is pretty cool!

This is really amazing!! Can have hot coffee even when you can't drink it fast. I'm glad it holds 14oz. The only issue I have is I can't update it on the app but it works great without the update. If the travel mug held more coffee I would definitely buy one.

A awesome gift for any hot drink lover. While it is alittle pricey, the product itself is good quality. The app is easy to use since you only have to set the temperature once and then the cup heats to that temp each time its turned on.

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.

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.

Gave this as a gift to my wife who loves having her coffee hot. Normally she would set her coffee down and when she got back to it, it wouldn't be hot enough. This would cause her to microwave her coffee 4-5 times. With the Ember, she places it on the charging coaster (which keeps it going continuously) and she can sip away all morning long.
