Customer Ratings & Reviews

Bought as a gift and the recipient LOVES it. They didn't really understand what it was until I explained it and now it is the crown jewel of their desk. The recipient uses it to warm coffee that has been in the pot too long. Uses the app to let him know that it is at temperature. Keeps the coffee tasting fresh all day unlike being nuked over and over again. No idea about the battery life as it stays on the coaster most of the time. Had to be reset once so far.

I work from home and while working I tend to neglect my coffee. I’ll go to take a drink and it’s cooled off. This mug keeps it nice and warm until I can finally finish it. No more trips halfway through to reheat my coffee in the microwave.

Works as well as advertised. Keep in mind that you do not want to leave the drinks in there for too long as you are essentially cooking your drinks. They will develop some strange flavors after enough time. The app works fine, but the mug is completely unusable without it which is a bit of a negative. Also a tad expensive for what it does.

The quality is extremely good and the app is easy to follow. I’ve had no issues so far and have owned it for a year. It’s easy to clean and move around. Battery life is fantastic. It’s good for at home or bringing with you to work. Highly suggest purchasing if you’re a slow coffee drinker like myself.

i bought this for my sister for christmas and she loves it. shes a big time coffee drinker (as am i, though im more of an iced coffee drinker and rarely drink hot coffee) and she prefers hot coffee, so i thought this would be perfect for her. once she opened it she was so happy because she had apparently been wanting one! this mug does so much, it allows you to choose your desired temperature and itll keep your beverage at that temp. you can use the included coaster to keep it charged/operating or use the internal battery in the mug itself. there is also an app you can download to fully customize and control every option with, which i recommend for all users of this mug because the level of control and customization with the app is great! but the app isnt needed to operate and use this, and you can still choose your temperature and stuff without the app! if you're unsure of what gift to buy someone and they are a coffee or tea drinker, definitely buy them this! they will love it!!

Sleek and premium! Coffee stays warm for long! Worth it and perfect for a gift.

I really do love this little mug because I’m really bad a making a cup of coffee or tea and forgetting about it until it’s cold. I can set my perfect temp and it keeps it there. My only complaints are the cup is smaller than I like and it doesn’t charge with something in it if you put it on the charger.

I have bought several of these the last 6 years. All are still working, But, the interior paint(?) in the inside is coming off from the only white one I have. The black one seems to be fine of the same age. You should also know the chargers start to fail after a few years, but can be fixed with a soldering iron if you are up for it. I recommend these to every person who asks about it

Bought this as a gift for someone else then later get one for myself. It’s an indulgence, but it’s so nice to casually sip my coffee or tea and it stays perfectly hot to my liking. It takes a bit to get used to the instructions and the battery life isn’t very long but if you keep the charging coaster nearby (I keep mine in my desk) it’s not an issue. I don’t like drinking out of travel mugs so this is really a nice “treat yo self” type of item!

I am a slow coffee drinker and this is a life saver. I have one at home and at my office. No more sipping on room temperature coffee.

The cup does a fine job at keeping my coffee at the specified temp but the app does not stay connected. Its perfect for me since i only use it for coffee but if you want to change temps for tea or something else you'll need to re-pair the bluetooth every single time. I'm using a pixel 6 pro.

The cup does what it says and will keep your drink at the temp you want for a couple hours while off the charger. One call-out, if you don't get it put on the charger perfectly, it won't stay charged. Not a huge issue but, a watch-out. You will realize it the first time you go to grab it and it is dead but, has been sitting on the charger overnight. I would probably buy again and if the price comes down, I would definitely buy again.

My husband bought this for me for Christmas. I work all day at my laptop, and I'm always complaining that by the time I drink my coffee, tea, or hot chocolate, it is completely cold. This cup works are claimed, and will keep your drink warm until you finish it. My only complaint is that it is small (which is why I took off one star), and it only holds 8 ounces. I think they might make a larger one, and wish I had a larger one.

Wife loves it. Keeps her coffee at just the right temp! Where she used to have to microwave just to finish a cup of coffee, now thats a thing of the past!

The only heated mug you'll ever need, honestly. This is a fantastic little thing that seems to heat fairly reliably. The only hitch is that software is dependant on the bluetooth ability of your phone, so connecting can be finicky at times. But it does indeed keep your beverage at the temperature it stays at better than any other similar cup of same value or less.

I gifted the Ember Temperature Control Smart Mug² – 10 oz in White to my wife for Mother’s Day—she’d been wanting one for over two years, and it didn’t disappoint! Sleek, well-designed & app-supported – The app lets you fine-tune the temperature, choose LED colors, and even use steep timers and presets for different drinks.

This was a perfect gift for my dad and he loves Joe it keeps his coffee hot

Amazing cup. It keeps it perfectly warm and last the whole time I'm drinking it. Very easy to clean and have ready for every cup of coffee I have. I'm already planning to by one as a gift for my spouse.

This cup keeps your coffee at the exact temperature that you like. You can set the temperature hotter or cooler than the factory preset temperature. It keeps your coffee at the temperature you enjoy for several minutes until you get your refill.

Got a couple of his and hers ember mugs abd the light is so cool and works great in leeping tea or coffee warm!
