Customer Ratings & Reviews

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.

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.

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.

Mug shows charged to %100. As soon as I take it off of the charging coaster the percentage drops below %90. It doesn’t last anywhere near the advertised 80 minutes at a setting of 136 degrees. When on the coaster the battery still dies if keeping coffee hot and will randomly shut off saying the cup is empty. Notifications show up continuously once the beverage has reached your set temperature. I had to shut them off. I have attempted to contact Ember 3 different times for support with absolutely no success. They never follow up or contact me at all. If it stopped working tomorrow, I would not spend the money again. For the price, I had hoped for a higher level of service from Ember. Realistically, I might have been better off with one of the cheap ones from Amazon.

Got this for my partner as a gift and he loves it. Keeps coffee hot and is nice looking on the desk when WFH. Can't be run through the dishwasher and they recommend not using a metal spoon inside, just minor adjustments to be aware of if you're coming from a non-smart mug.

Works well to keep coffee the exact temperature I like. Easily controlled with app. If not on the charger the battery is enough to keep coffee warm about 75-90 minutes based on my experience. Easy to charge just put it on the charger stand. Easy to clean with soap and water.

Let's be honest - the vast majority of people don't need anything like this and it's very expensive for a coffee mug. But I'd be lying if I said I didn't love having it. It's user friendly and just works. Come back an hour later and your coffee is still at that perfect temperature without the burnt flavor you get from other coffee warmers. I do wish it used a wireless charging solution to improve water resistance, and I think a 16-18 oz size would work better. (Note that while it's 14 oz, it's really more like 12 oz of usable space unless you fill it to the brim) It's also worth mentioning that the last few sips can sometimes get much hotter, but that's just because there is so little liquid left so any heat added will jump the temperature more. Not a big deal, but a minor annoyance.

We love these mugs. My wife has one and I’ve purchased one for several friends for birthdays, etc. We haven’t gotten to test this individual mug out yet, because it’s a gift for someone in October. But if it’s anything like the other ones, we will love it.

My wife takes a long time to drink a cup of coffee and she doesn’t like it when it’s warm. This cup keeps her coffee hot for as long as it takes her to drink a full cup of coffee.

Great product for the wife. She loves it so much. Great gift. It’s cool how you have control and options.

Very elegant and easy to use mug. Only minor complaint is that I wish the battery would last a little longer. I set my coffee at 137 and it keeps it hot for over an hour off the charging base.

This is a really good product. Keeps my coffee hot when I get distracted by work. Normally I would be irritated when I would get back to drinking and it was ice cold. Not anymore!!

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

I like to size and look of this smart mug. Plan to use near charging source if plan to drink more than 2 cups away from charger, as it does not keep beverage heated for longer periods of time. Can definitely sip a couple cups casually.

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.

Got this for my wife as a Christmas present. It does a nice job of keeping her coffee warm. Kind of expensive, but it's definitely a "luxury" item. After a few months of use the mug is still in great shape and has held up well to sink washes.

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

The cup is small and it’s easy to use, but the battery life is not as long as I would like for it to be. Overall, it was a good purchase though for the cost.

If you're looking for a gift for coffee lovers, search no further. The mug keeps your coffee hot for a long while and looks super sleek/modern. Just don't use metal utensils to stir.

Purchased for my wife and she loves it. It is Elasy to use and works as advertised. A teally great product for those who don't want their hot drink getting cold.
