Customer Ratings & Reviews

Purchased for my significant other. She loves it, it keeps her coffee at the perfect temperature. Keeps charged for long periods of time and is easy to charge again when needed. Easy to clean and maintain.

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.

Gave the Ember-Temperature Control Smart Mug-14 oz to my son for a birthday gift. He loves that it keeps his coffee at just the right temperature, due to covid he's working from home and he keeps his house pretty cold in the winter. The Mug makes a perfect gift for a techy coffee aficionado.

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

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.

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 purchased one mug as a Christmas gift for my partner and one for myself. We both love these mugs! The app is very easy to use. The mug is nice to hold; feels good in hand. Finally, our after-dinner tea is held at the right temperature while we watch TV. I highly recommend this product. A suggestion: by the 14 ounce 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.

$129 for a cup seems pretentious and expensive, but I strongly recommend it, I almost never finish my coffee drinks when they get cold, but with this cup I enjoy it a lot more, I am getting another one for office I wish they make it a little cheaper though

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.

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.

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

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.

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.

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.

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.

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.

As advertised keeps coffee at a specific temp that is flexible to what you want, easy to use. Downside is you cannot use regular silverware, it can scratch the coating. I use wooden stirrers and it works fine.

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 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.
