Customer Ratings & Reviews

I was worried about the day I would eventually drop the mug and possibly watch it shatter. Well that day finally arrived, yesterday, dropping it directly onto my concrete driveway from about 3'. I saw it hit, expecting it to shatter, but it didn't! Still fully functioning with only a couple small scratches. I thought it was ceramic based but it appears to be metal, maybe aluminum, by looking at the scratches.

Love these things. This is my fourth one and I've been happy with all of them. They are great if you're not the type to drink your coffee fast, they keep it warm for a couple of hours, or all day if you have it on the charging coaster. I highly recommend them. A little expensive when not on sale though

This is our fourth ember mug in our collection and we use them daily. The battery lasts a decent amount and being able to set the exact temperature really puts the icing on the cake.

As most of us know, coffee is much more effective when it’s hot,  I work from home, and throughout the day, I used to put my coffee in the microwave 5 to 10 times a day and that ended when i got this smart coffee mug that allows me to set my preferred coffee temperature through the app on my phone. And it notifies me when that set temp is reached. The app works great, seamlessly connects with my phone with instantly. Its a game changer in my coffee life.

My wife loves it. She's a sipper, I'm a gulper. Her coffee has been hot all morning. She even takes it down to the bus stop and folks ask her how her coffee is still steaming when its freezing out!! So, yeah, she loves it. I clearly haven't been able to try it yet, because SHE LOVES IT SO MUCH. It took a few tries to learn the right temp settings to keep her Nespresso from getting a film, but she's found it and there is no turning back. (Might be a little pricey, but got it on sale and her smile is worth it)

I bought 2 of these, one for my mom and one for my mother in law and they both adore them. It’s a great way to keep coffee hot, and super easy to use. Perfect gift for the hot coffee lover in your life.

I was always on the fence about getting this mug but after getting one I do not regret it. There are plenty of times I was unable to finish my morning latte and I would just end up drinking it cold or like warm. But after getting this mug I can now enjoy it warm all the way until the end.

I love this cup, my drinks stay at whatever temperature I set for the entire cup down to the last drop!!! This is an excellent gift idea for anyone.

My husband and I each received an Ember mug as a gift. We weren't sure if they really worked. They do! We've been using them for over 2 years and love them! I'm a coffee drinker, but also drink tea. I'm able to set the temp that I prefer for whatever I'm drinking. We use them every day and recommend them to anyone who enjoys their coffee or tea the same temp with every drink.

Works like it is advertized. Keeps the liquid hot for a long time

Bought this as a gift for a family member for Christmas, and the recipient really likes it for their tea. It is very well insulated on the outside so you don't burn your hands holding the mug like some others. Only complaint is that the battery life isn't the longest, but I saw that the lid you can buy may extend it to a certain extent, so that may be worth a try.

It's a nice mug that may keep your coffee warm, this is for someone that needs it for additional hour (or 2 if you're pushing it) of good coffee (or tea, whatever you prefer). However, the battery isn't that last-longing. You have to charge it every usage. and that takes around 2-5 hours depending your habits and how often you charge your mug. If I have to be honest, I think you're better off with a double-insulated tumbler/mug that may keep your drink warm up to 5-8 hours a day.

This is the second ember mug I've owned. I had to get a larger one because I enjoyed it so much. Get him when they're on sale. Novel product but thoroughly enjoy it.

Great cup! Keeps my coffee hot for at least an hour. Easy to clean

The coffee cup is a neat concept. Is it worth $129? Probably not but it does keep my coffee hot. Saying the battery lasts 80 minutes is very optimistic. Keeping my coffee at 140 degrees give me about 30 minutes before the red light comes on and it no longer warms my coffee and I have to put it back on the charger. Finally, you need to download the app to be able to adjust the temperature. I would prefer a "dumb" version where I could adjust the temperature on the cup itself.

beautiful mug! Love the color. The temperature control is perfect!

Had a few issues getting setup with the app but once that was settled it works great and keeps coffee hot. Very expensive.

Ordered the blue Ember mug online. Shipping only took a couple days. It works well. The app is easy to use. Having hot coffee or tea from start to finish is fantastic!

Christmas present for the Wife. She has been wanting one for a pretty long time. Seen a few reviews showing that the interior coating coming off and my only guess for the reason for that is that maybe they used a frother. Anyways this only gets hand washed and it is performing like an absolute champ. Do wish that they had a 20oz that was not the tumbler though.

The mug is a nice design and weighs about the same as a regular coffee mug. Coffee does stay hot but if you dont pick up the mug for 2 hours it will shut off. Overall its a great product.
