Customer Ratings & Reviews

This mug is amazing! I love that my coffee stays hot without scorching it no matter how long I am distracted from it. My only thing is that the battery life could be better. But for me it's no problem as I have my charging coaster right where I sit in the morning.

If you or a loved one are a hot beverage drinker, this is the best gift ever. I know, you are probably thinking...$150 for a mug is insane. But it's an indescribable joy. Hot coffee. For the whole cup. And for those of you who say you don't have this problem, you probably do and don't even realize it. Because this is piping hot, the whole time. Not just kind of lukewarm when you get to the bottom of the cup. Your last sip is just as good as the first. It's a great gift. It's expensive, but it's a luxury that I don't regret having in my life.

When the package says to start at 135°, believe it. The cup and coaster are great for the work-at-homer, it’s not overly large and bulky. The cup has a nice weight to it but, is not to heavy when filled with liquid. Overall, I would purchase this again as a gift

Solid cup. Keeps drinks warm. Unfortunately it's not dishwasher safe.

I bought this as a gift and she loves it. She keeps it at a decent temp and it lasts about an hour. For her that is perfect for others that may not be enough time.

Awesome self regulating mug keeps your warm drinks warm to temp you like for a long time. Well worth it wish it came with two charging coasters. App makes easy setup and pushes out firmware updates to yes a mug.

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.

This cup is incredible!! Any serious coffee drinker should get one. Your coffee stays hot for about an hour before it needs to be charged. If a person works, you can connect the plate to electricity from your desk, you can continually have HOT coffee all day.

Pros: Mug - Sets and holds the temperature of hot liquids really well. I set my coffee for 126F (52c) and it's at a good drinking temperature without getting colder. Good for all day sipping. - The mug doesn't get too hot. It'll get warm but definitely no where what I would expect. - The handle feels nice and I can slip 3 fingers in there. The edge is sharp but definitely not something to worry about and adds a bit of class to the presentation. I like the handle. - The mug fits perfectly on the coaster so there's no guessing where it needs to be placed to charge.

I like this one better than the regular ember mug which is around 10 oz. Honestly, if you work at an office or work from home, this is a must. Helps keep that coffee warm so you can be as productive and efficient as you need to be.

I would simply state it works as advertised. The mug keeps your liquid warm down to the last drop. The con for me is the price; a little steep for a mug. Even if it is a smart mug.

I love this mug. I bought one first for my wife then ended up purchasing one for myself. When you get this mug, you will ask yourself why no one else thought of this idea in the past. It is a little pricey (I think the 14 oz should cost $99 at max).

Got this as a present for my husband for Christmas. He loves how he can take his time drinking coffee and it will stay hot for a long time. Only thing is you must charge it every night.

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

Does exactly how advertised. Keeps drinks warm. One downside is that the battery runs out quickly. Orher then that product is good.

At the suggestion of my daughter, I got this for all my adult kids, myself, my sister, and my husband for Christmas. I would’ve considered it a frivolous purchase. It is not. It keeps your coffee nice and warm the whole time you don’t think you need it, but you do. The only thing I can’t speak of is how long it lasts. I also had to buy another charger and that was worth it too, just to have one upstairs and downstairs. Until you have one, you just don’t know. It’s like when the microwave came out.

I got this as a replacement for a 10 oz mug I purchased 2 years ago. I always felt it was a little too small for my coffee consumption. It works a advertised, but since I take my coffee with milk, the heat makes it form a skin which is disagreeable, but not the fault of the mug. I have used this recently with tea (no milk) to get me out of a cold and it has been great at keeping the temperature hot enough to soothe my throat. Hope to buy a travel mug when they are on sale, those things are expensive!

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

Great looking coffee mug however aside from looks, the functionality can be a bit better. Heads up for future purchases if for whatever reason you reset the mug by pressing the bottom button intentionally or unintentionally for more than 5 secs and see the colors flash.. that does mean it's reset the mug settings and you'll also need to manually reset your Bluetooth pairing from your mobile device (meaning forgot the device and then re-add as new device) in order for it be reconnected after reset and fluid detection to work. For the longest time I could not figure out how a filled coffee mug would read as empty. With that the battery life does struggle to lasr for my two hours of heated content sitting out on desk. So be prepared to have charger ready for charging if intended to keep intended temp for longer than that.

Now I don't have to reheat my morning cup of coffee in the microwave. This Ember keeps two cups at the right temperature all morning long. I have to remember to place it on the charger each night so it is fully charged in the morning.
