Customer Ratings & Reviews

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.

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.

Mother's Day replacement for white Ember that bit the dust after two years of HEAVY USE. Wife LOVES LOVES LOVES her Ember and wouldn't drink coffee any other way. Blue Ember on sale for a price I've never seen before. Easy pickup and perfect for wife for Mother's Day.

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

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.

I've been using this mug for nearly a month now, and I can honestly say it is the greatest splurge I've ever allowed myself! It will keep my coffee piping hot for about an hour and a half away from the charger. I keep the charger near where I sit "most" of the time for my coffee time, and using the charger as a coaster, it will keep it hot as long as it's there. Using the app will allow you to choose the perfect temperature preferred. I believe 140 F is the max, but I've found 135 to be my sweet zone. If you use creamer, I highly suggest spending a bit more for the 14 oz option! I make 10 oz of coffee with my Keurig and with the cream added, 14 oz is the perfect size. I absolutely LOVE this mug!

This mug is wonderful. Every cup of coffee stays at just the right temperature and the cup recharges quickly. Took one star off because it will not stay linked to the Ember app.

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

On sale completely worth it. Easy to use with app, always keeping coffee the perfect temp. The color is really nice too.

This is a great mug for the all day coffee drinker. The battery life is not great so make sure you leave the coaster style charger nearby. Very high quality and easy to clean.

This is a very cool piece of technology. If you can wrap your head around a $130 coffee mug this does a great job keeping your coffee as warm or piping hot as you want it to be. I do notice that the battery life after being removed from the charge pad at a full charge does not last more than a couple of hours, so the best way to use this is to use it constantly with the pad to ensure it stays on. The mug does not insulate the coffee any more than a normal mug once the heating element is turned off. Overall, worth it if you can keep it on your desk and it will keep coffee hot all day. Otherwise, you may be better served with an insulated travel mug like a Yeti or some brand of that sort.

These mugs are decent. They keep your drink somewhat warm for up to ~an hour and a half, even if you have it set on the charging pad. The heating element is located at the base of the cup which creates more of a temperature gradient, which is pretty noticeable if you have a full cup of coffee. If you have a milky drink like a latte in it the milk usually burns a little at the bottom leaving a fatty residue, which isn't a big deal but it isn't ideal. Ultimately I find these mugs to be overpriced and not worth it when you can get a really good thermos for a fraction of the price and it will actually keep your drink warm longer given the limited battery life of the mug. It's unclear how long the batteries on these will last. It could be that over a year or Overall, these mugs aren't quite worth the price, though I really wanted them to be.

It definitely works as advertised: your coffee stays hot until your last sip. However, it does come with a price tag just over $100. That being said, it's a splurge I do recommend if youre a big coffee or hot tea drinker - its so worth it if you are.

Every sip is like the first, fresh, warm and freaking exhilarating. This cup is amazing. It truly provides "the perfect sip" every time. Only problem is the battery goes dead relatively quickly... approx 90-120 minutes. I'm a 2-3 cup guy. The first 1-2 cups go down in the first two hours I'm up. Then I kind of slowly drink the 2nd or 3rd cup until about 10:00 -11:00 am.

Sleek and beautiful! Works great to keep your beverage at the drinking temperature you prefer. Very easy to use.

I wasn’t sure if I would actually use this but I use it everyday at work!! I set my temperature on the app & I don’t have to worry about my coffee getting cold!

Docked a star for the price, but if you're willing to spend the money, this mug is amazing! Nothing like having hot coffee at your desired temp for hours if you choose (by using the charger as a base). Using silicone spoons to stir due to the endless number of peeling reviews out there, but no issues so far

This cup is incredible!! Any serious coffee drinker should get one. Your coffee stays hot for about an hour before it needs to be charged. If a person works, you can connect the plate to electricity from your desk, you can continually have HOT coffee all day.

Love the size, color and style. Keep liquids hot all day.

My wife loved it, her coffee at the right temperature and stays warm from the first sip. Made of good material, great look and easy to clean it. Noticed there were several options in colors and sizes. It’s the kind of gift that will be used and not put aside. I don’t know if it can be engraved, which would be great.
