Hot coffee = happy Dad
Instructions were lacking for the set up for the product. Directions that came in box were scant, but after going on line was able to set it up. Hence the 1 star deduction. It is a tad overpriced but my Dad loved his gift.

Love My Ember
I received my Ember mug as a Christmas present and I have to say I am more than impressed. It keeps my coffee hot until I’m finished or it’s empty. I have wasted more cups of coffee because it cooled down. Not anymore!

Love it but coating wears down
My ember mug is one of my favorite things I own. I've used it daily for 1 year and 7 months. The app functionality is fantastic. The one down side is that, less than 2 years after purchase, the coating has worn down significantly on the base inside of the mug hear the heating element. Metal is now exposed on the inside of the cup and around the rim. I have closely followed care guidelines, only ever hand washed and do not use spoons / other utensils with this, so I'm not sure why it has worn down already. At this product's price point, I would have expected higher quality over a longer period of time.

Love it!
This keeps my coffee HOT! I had to get this because my coffee would always go cold quicker due to the creamer.

Okay I love that this mug can keep my coffee piping hot. I hate that it can only do it for an hour before the battery dies. I charged my mug overnight and it still fizzled out. For a mug this expensive, I’d expect a longer lasting battery.

Great gift
Bought this for my wife on Christmas. She loves it, keeps her coffee and tea warm while she gets ready for work or during long work meetings.. it’s only been about a week, but no complaints thus far.. the app helps you set temperatures suitable for you.

Garbage
This product is just frustrating. I spend more time fussing with it, the bluetooth connection and just trying to get it to turn on and figuring out what pattern of lights means just on. I have to re-pair the thing every time I open the app I think all the options and the app might be great if you had a product that actually worked

Needs work on the ceramic
I received this cup as a gift in October. I have the white one. Unfortunately, from using a spoon, the whole bottom the ceramic is gone. The metal is showing through.Couldn’t get any help because I didn’t have a receipt to prove it. The cup worked great for about nine months and then it just wasn’t working properly. Make sure to use a wooden spoon if you were going to stir anything into your beverage..

Worthless…max temp is 145
Worthless! Mug won’t heat above 145…I still have to heat my coffee in the microwave in a separate mug every 30 mins to reach my desired temp of 165.

Gimmick coffee cup
It's a gimmick item. Works great for a while, but when the rechargeable batteries reach end of life, you're stuck with a coffee cup that's just like any other cup, except it shouldn't go in the dishwasher. Plus, the flimsy pins on the recharging pad - do take care in setting down the cup to charge, and keep the bottom of the cup very clean. Poorly designed/very fragile. Overall, the fact that you cannot easily replace the rechargeable batteries is a major turn off for every buying these again. Would also add a ding on the cup volume - using a K-cup on a small/medium/large type of Keurig, there is very little room for adding anything when using large (12oz).

Flaking coating - gently used
I have issues with the coating flaking off on the inside. I've always hand-washed the mug and only use plastic utensils. it's only been a few months and very disappointed with the flaking coating.

Nothing but issues
Doesn't charge past 75% and have to repair the mug to the app every time I turn it on. Seems I'm not the only one who has the issue according to all the reviews on the app.

Toxic mug?
I like the idea but there are two problems with the mug I got. First, the charging pins stick so that you can't make good contact between the coaster and mug to charge. I had to try a fix this with a dab of solder to raise the pin higher. Second, after a few months the coating started to come off. At first I was not concerned but then after using it for several more months I went to clean it out (hey hot coffee-- I just rinse) and all the coating came off the inside. So apparently I was swallowing the paint all this time. They claim it is ceramic, but ceramic would not peel off the way this stuff does.
