Customer Ratings & Reviews

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.

Holy cow, I should not love this mug as much as I do, but I do. It's a total luxury to be able to set your coffee temperature down to the degree and then have it there for more than an hour. I use it every day, and despite the lofty price tag, I have been tempted to buy a second (one for work, one for home). I haven't gone there yet. My only small gripe is that the mug needs resetting once in a while, and the only way to figure out when that is is when you take a sip and find that the coffee is cold (i.e., the mug failed in its one job of keeping your coffee at the right temperature). In that case, you have to go through the typical bluetooth nightmare of re-pairing the mug. I suppose this is a complaint about bluetooth and not the mug, but still, it impacts the experience slightly. But overall, I totally love this mug and what it does. p.s. I've tried one other heating mug. That one worked by having a wireless pad that heads the mug from beneath. It was not nearly as functional as the ember.

We originally went for the less expensive 10oz, but don't, it's too small. The 14oz is just about right. Once everything is synced up with your phone this little guy works like a champ. Literally will stay at the exact temperature you set it up. It will increase the temperature up to a higher temp if need be. Exceeded my expectations.

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.

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 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.

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.

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.

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.

It works exactly as i expected, and its just amazing. Not a lot of battery, but just leep the charger nearby.

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 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.

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.

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

This cup definitely keeps the drink warm much longer. Which is exactly why I got it.

Bought this mug for my wife who is a tea enthusiast and she loves it. Easy to use and does a great job with keeping the tea up to temp. Cool product!

$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

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.

Excellent quality product & on time delivery. The coffee is hot for as long as I need to continue my work & sip when i need.

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.
