Mug works but does not hold a charge for very long. I bought it to keep my coffee warm while I’m getting ready for work which is about 90 minutes. Even when fully charged, it doesn’t stay heated. It may work fine if you keep it on the charging coaster but that defeats the purpose. For the price, it should stay charged longer.

This Ember mug is AMAZING!
I received an Ember mug as a birthday gift, and it’s honestly one of my all-time favorites. I love it so much that I’ve since bought three more as gifts—for my son, daughter-in-law, and sister—and they all love it just as much as I do. Yes, it’s a bit on the expensive side, but for me, it’s absolutely worth it. No more dumping out cold coffee or settling for reheated coffee that just doesn’t taste right. I can actually enjoy my drink at the perfect temperature from start to finish. It’s already paid for itself in saved coffee and daily enjoyment. If you’re on the fence—don’t hesitate. It’s a game changer!

Ember love
Love the new edition Ember. I had a 1st generation one for a long time. It was great but not holding a charge very long. This definitely does and love the green! So happy Target had it on sale.

Buy it if you like to keep your coffee hot
Keeps my coffee warm. I hate that it takes time to charge and that I have to alway hand wash it, but I love how hot it keeps my coffee. I sometimes keep it on the charger when I’m working. I also charge it over night for the next day. It is lightweight and has a thin lip at the top. Two important features I look forward to in coffee cups.

Don't buy
It will say it’s empty when it’s full. It will say it’s a a warm temp when it’s cold. If you want it or warm at max temp, it lasts less than an hour. have had it 2 weeks and rarely has it worked as expected.

Keeps it hot
I bought this for my husband for Christmas and he loves it! It’s the only mug he wants to use for his morning coffee and he’s super bummed if he leaves it in an odd spot and forgets to wash and charge it. The charge has been good for our long morning’s worth of coffee drinking, it needs to be charged between uses/coffee sessions, but that’s not surprising when you consider how much energy output it takes to produce heat. It’s cool that you can adjust the heat and see how much charge it has using the app. It’s perfect for anyone who regularly finds their coffee getting cold before they get to drink it.

Expensive and app is awful
Android app has 1.4 stars because it consistently doesn't connect, this product is basically useless if you have an Android phone.

Great idea but has its limits
It is nice to get down to the bottom and still have warm coffee or tea. It’s not perfect. Sometimes it tells you the cup is empty, even though it’s not. You have to have the mug, charger, and phone in pretty close proximity or you risk it not working well. Unless you are sitting still, it is probably not going to keep it warm for you all morning.

The App is super easy to use and the mug keeps the liquid whatever temp you want. The battery life does live up to what it says, however, it doesnt feel like it lasts a long time.

I am reviewing unpacking and setting up the mug since I have been so far unable to actually use it. It is packaged so that after 2 people attempted to master the box I just gave up and ripped it up. The instructions are more complicated than my husband’s small plane. Requires an app and Bluetooth pairing which has not gone smoothly. It is also relatively heavy. I hope if I can get the Bluetooth pairing to work that I will find its use as appealing as it initially seemed to me.

Its going back...
I've had this for a day- I bought the 14oz, however, it's not 14oz, it's more like 10oz if it's filled to the brim. 8oz if you want to hold it without spilling. Not sure why it says 14oz, I measured it. Also, I charged it to 100%, used it once for a pretty normal amount of time- discharged to 54%. I charged it briefly, it showed 84% (didn't seem long enough to reach that), I used it again and within the hour it was at 5%. I like it- but not sure it's worth the $100 considering how inconsistent this is. It dies pretty fast. Hard to wash. It's actually only about 8oz. 14oz I would keep it, but since it's only 8ish, it's going back.
