Customer Ratings & Reviews

In general wonderful! I sit at a desk for long periods and this will keep coffee hot for well over an hour. The only problem, is that its almost too hot. I know there is supposed to be a way to control temp on the app...I'll have to look into that. The button on the bottom is a bit touchy but it works.

Got this as a long time coming gift for my wife! She has wanted one for years but never as much as this year! With our first baby this year and coffee became her life blood, so she talked about this more. Works as expected. Fairly short battery life, but considering you should drink through a cup within a reasonable amount of time I would say the expectation matches the pay off! Great product, easy to use, app is smooth. Glad I got this for her, finally!!

I absolutely LOVE this cup! I actually look forward to using it every morning at my office. I usually drink a couple of cups of coffee each day and usually have to heat it in the microwave a few times before I finish each cup. This cup keeps the temperature at exactly the temperature that you like. I've tried various temps and the default of 135 degrees is the best. This cup is not meant to provide hours of charge off the base, however, it did last for a 1-1/2 hour meeting before returning it to it's base for charging. It's perfect for the office because I'm up walking around and back to my desk often, so it's constantly being charged again while I'm sitting at my desk, but still stays hot while working things out in the warehouse.

I am so please with this mug. I thought it would be similar to the electric cup warmers but so much better. I work from home and at times get distracted, when I return to my coffee, it’s cold. Not this one, it remains at temperature I set. If I have to run out I can carry and it’s the same temp as I set. Saves from wasting coffee throughout the day because I let it get cold.

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.

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.

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!

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.

A little costly, but worth it. Now I never have to worry of my tea or coffee going cold.

Works well to keep coffee the exact temperature I like. Easily controlled with app. If not on the charger the battery is enough to keep coffee warm about 75-90 minutes based on my experience. Easy to charge just put it on the charger stand. Easy to clean with soap and water.

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.

I purchased the Ember a week ago and i absolutely love the fact that it is easy to set up and use. The product works as advertised and keeps your drinks at your desired settings. I will be buying more as Holiday gifts. Taneisha Howell

Mug shows charged to %100. As soon as I take it off of the charging coaster the percentage drops below %90. It doesn’t last anywhere near the advertised 80 minutes at a setting of 136 degrees. When on the coaster the battery still dies if keeping coffee hot and will randomly shut off saying the cup is empty. Notifications show up continuously once the beverage has reached your set temperature. I had to shut them off. I have attempted to contact Ember 3 different times for support with absolutely no success. They never follow up or contact me at all. If it stopped working tomorrow, I would not spend the money again. For the price, I had hoped for a higher level of service from Ember. Realistically, I might have been better off with one of the cheap ones from Amazon.

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.

This product does really keep the coffee hotter for a long time. It really works.

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 have wanted one of these for years and did not want to spend the money. I work from home and end up warming up my coffee multiple times a morning due to meetings. I finally pulled the plug and am so happy I did. I love the fact that it keeps my coffee the perfect temperature until I am finished, and it is also very easy to clean.

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

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).
