Customer Ratings & Reviews

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.

Great cup to keep beverages hot and at your choice temperature. Lasts for over 4 hours off the charger. Sometimes it’s difficult to connect to your blue tooth. Other than that great coffee mug - love it! Would recommend

I actually love this cup. Although you have to keep it on its base, the cup itself doesn’t have a large battery to walk around with it for too long before it dies. Expensive. But awesome.

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.

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.

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

Wonderful coffee mug keeps my coffee hot for quite some time. I like the larger capacity. Definitely prefer the dark colored mug. An excellent investment.

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

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 like it. It keeps my coffee, warm and cold weather.

Love love these mugs! I have several and have given them as gifts, easy to add to phone, keep coffee super hot

Best cup for the busy day. Get distracted...no reheating. Your drink stays hot.

Pick the temperature that you want your coffee to be, and it will always be it! No more cups of cold coffee

A truly excellent temperature control smart mug, delighted to have purchased it, works great

Great mug. Love that it’s not hot on the outside but the drink is hot inside. It works great. I wish they made it a little bit bigger like 16 oz and somehow make it last a bit longer. But great concept and works very well. Coffee is hot till the last drop!

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 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...

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.

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.

Love this mug, especially running around with the kids, massively reduces the chance of me getting back to a cold brew. Love this mug!
