Used
I was very excited to get this for my husband for Christmas. Unfortunately, when I opened the box when it arrived, the Ember container itself was completely apart, and everything inside was splayed about the box. Upon reviewing the product itself, it appears to be used. There is a lip mark around the rim and a ring on the coaster. I plan to go to the store and inquire about an exchange. If not, I plan to return.

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.

Bad shipping?
Ordered this as a gift. When it arrived it seemed as though it had been opened and thrown back together. Pieces were not in the box and the mug itself was dirty. Disappointed.

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.

Never reconnects to app :(
Disappointing app experience. After the initial pairing the app will never connect to the mug. (Pixel 9 pro xl) You may think you don't need the app - but you do if you want to view battery life or change the temperature set point. One star based on this being a premium product at a premium price. Bugs like this are unacceptable at this price point.

So Happy!
⭐⭐⭐⭐⭐ Ember Mug – The Best Gift I’ve Used All Year I received my Ember Mug for Christmas in 2024, and after using it consistently for almost a full year, I can easily say it’s one of the most useful and well-designed gifts I’ve ever owned. From the very first day, it completely changed my morning routine. Instead of rushing through my morning drink before it cools off—or having to reheat it multiple times—I can set the exact temperature I enjoy and keep it there. It feels like having a tiny personal barista carefully maintaining my perfect cup. What I love most: Consistent temperature: My morning drink stays exactly how I like it from the first sip to the last. No reheating. No guessing. Just perfect. Beautiful design: Sleek, modern, and comfortable in the hand. It feels premium every time I use it. Long-lasting battery: I’m impressed with how long it holds a charge, especially after nearly a year of daily use. Smart features that actually matter: The app works smoothly, the temperature control is effortless, and everything feels intuitive. Surprisingly durable: After almost twelve months of use, it still works like the day I opened it. I didn’t realize how much a mug could improve my daily routine until I owned this one. Now I wouldn’t want to go without it. If you’re on the fence about buying it—or considering it as a gift for someone—you'll be glad you purchased it. Easily a 5-star product. One of my favorite gifts ever.

One Year Review
I've had this mug for about a year and use it at least 3 times a week. It works like it is intended to and I have had no issues.

Bummer
We loved them while they worked. But! My wife’s worked for 6 months and mine nearly two years.

Slimy residue on coffee and cup
I like the mug but it has one drawback. I nurse my coffee in the morning and if you use half and half, the mug seems to “cook” the half and half leaving a brownish slimy residue on the coffee which transfers to the side of the mug interior. Wouldn’t have wasted the money if I knew this.

Design Flaw
This is great when it works. The charging pad is a bad design. The little spring loaded pins break or stick which then prohibits the mug from charging. It is a manufacturing problem, but they don’t care as long as it works until the warranty is up.

Great until it wasnt
I loved it when it worked. After a month or two it stopped heating and the reset didn't work. It became useless

Just what I needed
Great cup for keeping my coffee hot. In your average mug, my coffee would get cold and I was reheating it on most days. I am delighted in coming back to a hot cup of coffee after getting breakfast started.

Not impressed
Second mug. This one is less than a year old and as with the first one not working no matter what I do. So will probably not get another one. Will stick with my Mr, Coffee mug heater.
