Customer Ratings & Reviews

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.

Use every day! Keeps my coffee and tea at a perfect temperature. Great quality.

Best cup for the busy day. Get distracted...no reheating. Your drink stays hot.

I love my Ember mug! This is my 3rd one. I am hoping they can increase the battery 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)

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.

I love that it keeps the coffee at the perfect temperature for me. The battery won’t last more than 50 minutes off the charger, but I usually drink it with the charger nearby so that’s fine. My only ding is that the charging pins stick after a while and it struggles to maintain a connection to properly charge

Boxes for my daughter because he makes her coffee and then she gets doing stuff and then her coffee she dumps it out she's only had two sips out of it now she can finish her coffee keeps it hot

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.

My wife loves it especially because she set it to the temperature she takes her coffee and stays hot while she is busy

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

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.

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.

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.

Love the Ember! My coffee stays at my desired temperature the whole day! It is a little pricey but I think well worth it. I wish more colors were available besides black and white.

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.

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

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.

It’s perfect for the morning cup of coffee. It keeps my coffee warm up to 30 minutes.,

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