Customer Ratings & Reviews

Bought this for my wife as a birthday gift and she loves it! She tends to abandon her coffee around the house when it gets cold on her, since gifting her this mug, no stranded coffees! She loves that she can adjust the temperature using her phone unlike some other coffee warmers we’ve purchased before. 10/10 would recommend.

I purchased a second Ember device for home because I liked the first one I got for the office so much. It’s simple to use and I look forward to slowly sipping my coffee. The only downside is that I should’ve splurged on the larger size. I tend to drink my coffee black but I do like to add milk to my tea. I don’t think the smaller size is adequate for drink and add-ins.

Great mug, keeps your beverage hot. I got the 10oz size, but the 14oz might have been a better choice for me. Only thought would be to have a more ergonomic handle. The thin profile of the handle is a bit tough to hold, and it’s a bit small for even my fingers to fit through.

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!!

I thought of this as rather frivolous - it was just a way to give myself something fun in the midst of the pandemic. However, it really does work and I use it almost every time I make coffee. I tend to get distracted and often end up throwing out coffee. With this, it's there, warm and waiting for me, when I get back to it. I do leave it on its charging coaster all the time if there is coffee in it. It has to have special handling - no dishwasher for it - and I wish it held a little more coffee. It only holds about 2 official coffee cups worth, not a big mug's worth

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 got this mug because my office is chilly and my desk is right next to a cold air vent, which always makes my hot drinks cold really fast. This mug keeps every last drop at the perfect temperature! I knocked off one star because setup was a bit if a hassle, the mug wouldn't stay connected to my phone (bluetooth). I had to reset the mug and reinstall the app several times. But once you set the temperature you want you don't need the app anymore.

Bought this for my wife and she absolutely loves it. She even bought one for her nephew. Perfect for coffee/tea lovers.

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.

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 bought this as a birthday gift for my husband. He loves it and uses it everyday. It's so convenient sitting on his desk and keeping his coffee at the perfect temperature all the time. And it washes really well too. You don't need to scrub it. Just rinse and it's clean again. And maybe because it's black, I don't see any coffee stain. I may consider buy one for myself.

I am impressed with the app. Has several presets of heating. You can save your own settings too. Choose color of led for identification. But more importantly, it keeps your drink to the desired temp. Use this with the coaster charger and you have yourself a hot brew throughout the day. I should have purchased this sooner. Heating drains the battery a lot. You need to use the coaster charger to keep it up and running. No biggie. It still is a coaster after all, blends well. Note: you might want to get the bigger cup.

This really keeps your drinks warm. So far no issues with the mug or app. The deal price was definitely worth it.

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.

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.

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 drink a lot of coffee, but recently I have found that my coffee gets cold fairly quickly. I thinks its because it get distracted at work and let it sit too long, but anyways i wanted to find a temperature controlled cup that keeps my coffee hot. I have had sometime with this cup and I love it. It always keeps my coffee hot and I have never had any issues with the product. Solid build and design.

Works as advertised. This is my favorite cup and I use it everyday. It keeps my drinks hot for most of the day. I would recommend it to everyone that likes hot drinks

I like having my coffee stay the same temperature to the last sip. I also purchased the lid for the cup.

Love that this keeps your beverage hot. The charge doesn’t last as long as I would like however it works well. If I was to buy again I would buy a larger size
