Beautiful and sleek design, but the battery...
I received the Ember mug as a Christmas present. Beautiful color and sleek design; however, there's an obvious flaw with the battery. Five minutes after being fully charged and removed from the charging coaster, the app displays 95% battery, and after forty-five minutes, it drops to 6%. It definitely fails and doesn't maintain temperature for 1.5 to 80 minutes.

Careful of easily spilling with rounded bottom
I've had this mug for a year and really love it. The only problem I have is the rounded bottom makes it so easy to tip. One slight push or nudge and it knocks over since the bottom is not flat. Mine charges fine and stays hot but I've knocked it over a few times by barely hitting it. Other than that mug is great. I don't use it for first cup of the day since I drink that one fast. But afternoon cup or a cup of tea to drink slow stays nice and hot. Nothing worse than taking a sip of cold drink that's been sitting a while.

Broke in 2 months
When it worked, it worked fantastic! Only lasted two months before it broke and stopped working.

Lid sucks cup ok
Stupid design on 16oz lid you cant tell if its closed or open or what side to drink out of. If you accidentally drink out of the wrong side coffee hits you in the eyes. It is worse early in the morning when its still kind of dark outside. Also you adjust the color but its never your color it stays mostly just white

Best gift!
This was given to me by my daughter because I was habitually allowing my coffee to get cold. I love this cup and have used it almost every day for several years.

Good Mug, Weak Battery
I like the mugs, but the battery life is terrible. 80 minutes for the large mug. and the battery drains when it's not being used. I charge it at 100% and overnight it will drop to 65%. Otherwise, it keeps my coffee hot and I like being able to regulate the temp. At the default temperature the coffee gets burned pretty fast. I keep it at 125º. Just need to beef up the battery life. Leaving the mug on the charger all dies sucks up electricity,

Disappointed
Got this at Christmas. Had to remove and re sync to Bluetooth every time I used it. Did not run while on the charging plate, and took nearly half a day to charge. Options were full refund or replace with a different color (no copper available at the time)

Company does not stand behind their product.
To all who purchase or own ember mug, beware, they do not stand behind their products. If something goes wrong. I've owned 2 mugs, and I had issues 3 times within a 1 1/2 year and they did not stand behind it twice, the mugs stopped working. And stopped connecting to your app. The heating plate stopped working, and now my mug again is not communicating with app and their resolution is will give you a discounted price

Worst app and makes mug useless
I got the mug and it worked for a few times in a short period of time. In recently months I haven't been able to connect it. I followed the available instructions and reset the app and data many times but the mug just sits on my counter wasting space.

Don't Waste Your Money
It stopped working 2 weeks after 1 year. Company was not helpful. They said after a year, buyer needs to pay for repair. Disappointing for the price point.

Defective
I have purchased two of these and for awhile (last one worked for only three months) and both have malfunctioned for the same reason. The pins on the coaster break down and will no longer keep the cup charged. When they worked they worked great. Unfortunately, they don't last very long before this defect renders them useless.

Not worth the money
The mug does not hold a charge long at all; 40 minutes or so. Definitely not at all worth the high price tag.

This mug is an absolute must have!
My first Ember 14 oz mug lasted 3 years to the week after being used 3 times a day. The mug was still in perfect condition but the battery died. The charger pins gave out after a year or so on the coaster so I did have to buy another coaster. I have had my second Ember cup for 14 months now and it is still in perfect condition. I plan to buy another one soon to keep on hand for whenever this one dies because I simply cannot be without this cup. I absolutely love it! I like to linger over my email in the morning while enjoying my first cup of coffee and now it stays hot for over an hour. I rinse it out under running hot water and wipe clean with a sponge and carefully dry with the dish towel before putting i back on the coaster. I have had no issues with peeling or stains as some people have reported.

paint loss in the bottom
After using it for a year, my mug has started to lose the paint from the bottom. The problem is that I'm ingesting this paint. It's true that it doesn't cause me any problems while using it, but what mug gets damaged using ordinary metal spoons? I don't recommend it for the price; it's not worth what it costs.

Good gift for those that forget about their coffee
This was gift for my husband for Christmas. You can control the temp of the cup with an app which he loved. Very sleek and simple design

Another broken one
This is the third Ember mug I purchased. And as of this morning, this one doesn’t work. I used it maybe 3 months. Like the 2 before it, this one just stopped for no apparent reason after just a few months. I really liked it but I won’t be buying another one.
