Customer Ratings & Reviews

If you're a slower coffee drinker like me, this is the perfect solution for keeping your coffee warm or hot the entire time. I usually sip on my coffee for an hour (sometimes more) and this cup does a great job at keeping it hot. You can set the temperature you want in the smart app and the cup will do everything for you. Easy to clean and return to the charger for later or the next day. I liked it so much that I purchased one for my son to drink his hot chocolate during the winter.

Love it! I don’t drink my coffee very fast so this is great to keep my coffee warm while I drink it.

Great coffee mug for my WFH mother! No more having to get up and go to the microwave to keep reheating. Keeps it hot and fairly fresh vs that reheated coffee taste

For a slow cafe drinker like me this cup is amazing, I follow an IG account and realized she had one of these and got me curious to wanted to try, Keeps my cafe warm without having to reheat and that I like a lot.

I never thought a coffee mug would be something that I'd review, but this one left me with (almost) all good things to say. The design is super sleek and the ceramic is a nice feel. The bottom conductors matches with the design perfectly and the mug stays charged for A full day, if not more. My only concern is that after making your 10oz sized coffee in a Keurig, then adding creamer and sugar, the coffee rises right to the lid.

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 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

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.

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.

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.

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

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.

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.

Bought this a gift for someone and they now use it almost every day. It keeps whatever you are drinking at a very stable temperature. The only issue that this product might have is the battery life, but if you keep it on the charging pad at least some of the time you will not face any issues.

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!

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

Works great and can sync up to phone and iwatch to alert when desired temp has been reached.

I got one as a gift and oh wow! I love that my last sip of coffee is as hot as my first. I drank out of it every day. It lasted for years! Their customer service is TOP NOTCH. I wish every company and product were as good as this one!

I give it four stars because number one I didn’t want to download the app. Never too it doesn’t hold that much. It’s one cup that’s it But oh, what a relief it is to have a nice warm cup of coffee .
