Customer Ratings & Reviews

Great coffee mug. This is a great idea that I’d put to use. The wife lives having hot coffee while she works from home. It keeps it hot all day as long as it’s on the charging coaster and will keep it hot for about 90 minutes without it on charger. Very easy to set up in app and the cup sleeps when not in use and wakes when you use it. Don’t need to use the app except to change temps if you want to after initial setup.

Got this on sale for $99 and it was very nice. Great construction however if you are a huge back-to-back coffee drinker, you may want to consider that the battery life is about 80 minutes and you may want to purchase multiple bases/lids for it. Great concept though! Wish the battery was a little bit longer, but for how light the cup is, I can’t complain.

I am in love with this thing. I am a devoted Nespresso user but sometimes the coffee isn't that hot, even when it's right out of the machine. This is the perfect solution. Gets the coffee to the right temperature (without losing the froth) and keeps it there until I'm done. My only complaint is that you need to recharge fairly quickly if it's not on the saucer, but other than that, it's perfection.

I purchased the Ember mug as a gift, but I subsequently received one myself. It only took a few minutes to set up the mug to my specifications via the app and plug in the base; that was all that was needed to begin using it. The mug comes out of the box with a slight charge. I appreciate that I’m able to adjust the temperature depending on what beverage I’m drinking. Easy to clean. Best purchase/gift!

I’ve been using the Ember Smart Mug every day since I bought it, and I can honestly say it’s a game-changer. I used to constantly reheat my coffee, but now it stays at the perfect temperature from the first sip to the last. The app is super easy to use, and I love being able to set my preferred temp (135°F is my sweet spot).

Really nice and sleek cup! Keeps liquid hot! Very good!

My Ember mug stopped charging and working after about 12 months. Luckily, I had Total Best Buy Protection, which replaced the product. The only surprise was a $29 deductible, I didn’t realize that was part of the plan. In hindsight, I might’ve tried the manufacturer’s warranty first, since that would’ve likely been free. Still, the replacement process at Best Buy was quick and hassle-free, and paying $29 was much better than buying a new mug at full price.

This is my 3rd mug in about 6 years. I use them heavily so the battery starts to wear out after about 2 years. I've never had any problems with the app, although once I sync and set my preferences, I never use the app again. I don't understand why you would want or need to. I have found the Ember mugs to be exceptionally reliable and have recommended to many family and friends.

This seems like an extravagant purchase but if you spend the extra time and money to making great coffee, this really makes a big difference in how it tastes. I didn't realize how much I didn't enjoy the last half of my morning coffee until I experienced what it's like when it's at the same temperature as my first sip. The only problem is I now find myself wanting more coffee because the end of the cup no longer puts me off. Product is well built, easy to use and is exactly as advertised.

This is my third cup once you have one it’s hard to do without it.the first one lasted about a year and a half the second one was new and didn’t perform as well as the first one so I took it back. The one I have now works so well the coffee burns your mouth. Great cup

Best Christmas gift to give anybody. I even have a temperature now I want my coffee now it’s 129 degrees lol. I love this

I really enjoy that the mug keeps my coffee hot for nearly the entire length of tha battery life. The app was easy to pair with my phone and i love the ability to control the settings from the phone.

Works well - keeps coffee from getting cold. Battery life could be longer but if you keep keep it on the charger then it’s not an issue. Price could be cheaper. App is not really useful at all.

If you ever need to complicate a cup of coffee, get one of these. The cup itself is great. Very sturdy…if not heavy. Keeps coffee warm…when it works. Most reviews on other sites fault this to the app, which is glitchy, at best. When I get annoyed, I revert back to my little coffee hotplate(which only cost $20 and works every time I turn it on), or the microwave…and you can’t use the Ember on/in either.

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 having my coffee always the temp I want! I never have to top off the cup to keep it warm!

There's really not much to say about this mug, but I will say a lot anyway. It keeps your coffee hot, and it does it well. It really is an odd sensation to get to the bottom of a coffee you've been nursing for 45 minutes and even the last drop is just as hot as the first. If you're looking at these reviews, you've already wrestled with the price and you're wondering if it's worth what you'd pay for it. Well ... No, not really. Yes, it does what it says it will do, and yes, I have an irrational love for this mug because it actually filled a need of mine (I am not a coffee chugger, and mine always gets cold halfway through). The setup was easy and I didn't run into any problems connecting to it. It takes quite a while to charge, but that's wireless charging for you (Ember, maybe look into fast wireless charging for the price you're asking for version 3). But can I tell someone to shell out this much money for a mug whose sole purpose is to keep your coffee hot? I can't. Maybe if it was a better, more comfortable mug to grip -- that scrawny sharp handle ... good lord ... quality mugs have thicker, comfortable handles. I wound up with a little funny money and a Best Buy coupon, so I bought something I would never in a million years buy for myself normally, and I am happy with this purchase *in that context*. Now, would it make an amazing gift for the coffee lover in your life? Yes! They'll go nuts over it, and you'll enjoy watching their skepticism turn to delight after realizing their coffee is still hot at the bottom of the mug! If you're a coffee drinker and you want to treat yo'self after 2020? If you've got the cash to spare, yes! You will love this mug! But just don't tell anyone what you paid for it... Also, make sure to get the 14oz -- I accidentally bought the 10oz mug initially because the silver one is the same price as the 14oz and I just wasn't paying attention to the box ... and in person, the 10z is tiny. Pay the extra and get the 14oz if you're going to take the plunge into the world of inexplicably expensive coffee mugs. Pros: It just works. An open mug of coffee still piping hot an hour later will blow your mind, trust me. Easy to set up, easy to use. Cons: Price. Price. Price. And also, the handle is the worst, I find myself just wrapping my hand around the mug because the handle just plain hurts to hold.

As advertised keeps coffee at a specific temp that is flexible to what you want, easy to use. Downside is you cannot use regular silverware, it can scratch the coating. I use wooden stirrers and it works fine.

It does what it claims to do. It keeps beverages at desired temperature.
