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.

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.

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.

Love this mug, especially running around with the kids, massively reduces the chance of me getting back to a cold brew. Love this mug!

Does exactly what its supposed to do. Keeps my coffee hot and is easy to clean/use. The only 2 compliants I have is that when the level of coffee in the cup gets low, it seems to overheat it which causes a bit of burnt taste and that the Ember app on Android will sometimes just not work correctly, requiring disconnect/reconnect or uninstall/reinstall. The app isn't needed all the often as you can just set your desired temperature and leave it.

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

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.

The app is very easy to setup. Works well and keeps coffee warm. Only con is it isn't dishwasher safe.

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

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.

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.

I've had my Ember for about 2 months and use it everyday! As someone who always has to get up and leave their desks, it can take up to 2 hours for drink my coffee. I would normally come back to lukewarm coffee which no one likes. Now my coffee is always at the right temperature. The one drawback is that the battery only lasts about 80 minutes and at which point it stops heating. Not that big of a deal for me as I have the charger right on my desk, but if your charger is not near by that might be an issue.

Quality product that my husband uses everyday. He was always reheating his coffee and now he doesn’t have too.

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.

Works as described and keeps coffee hot for hours. Easy to set up with app as well.

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.

Recently purchased. Battery might last 15 min on the pre-set temp. I really am not interested in putting the ap on my phone. Registerd the mug and put in a support ticket within 24 hrs of receiving this. Yes i did fully charge it. While it works... it is awesome. But frankly the coffee doesn't cool down much in 15min anyway. It has been a few weeks. No response from customer service at ember. I think i might still be in the return window... maybe not. I really liked the coffee staying hot, but a 15 min window and has to get back on the charger isn't worth it to me. I wish it did work for a longer time frame... support is nonexistent from ember.

Absolutely awesome to keep at the desk. Keeps temperature exactly how i like it. The battery is nice for not placing it directly on the base all the time but nothing else - runs out in 40 minutes or less. Bluetooth connection is iffy at best, but i rarely change settings. Wish it would have the controls on the mug itself.

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.

Expensive, but it does exactly what it promises. I was able to buy mine in the BB sale, despite wanting one for months just couldn't justify full price. Super easy to set up and the phone app lets you monitor progress and status. Value for money - depends on your point of view, but keeping your hot drink hot - brilliant!!!
