Love the mug! But honestly my only complaint is the size. Definitely go bigger if you’re going to buy one.

Pogo pins quit working.
Mug is only ok. Stains easily, ceramic coat slightly chipped even though I am careful. The worst part is the charging puck. The little pogo pins that are supposed to be slightly springy to contact the mug quit working. They have replaced it twice during the warranty due to only lasting about 4 or 5 months before they quit popping up to touch the mug. I will not buy another after this warranty is over and the quit replacing the puck free.

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.

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.

Durability Concerns with Heated Mug Coating
I've been using this heated mug for just over seven months, and unfortunately, the coating at the bottom has begun to flake off. I’ve only cleaned it with mild dish soap and a paper towel, so I’m surprised to see this kind of wear. It’s disappointing, especially given the product’s price and intended durability. I also hope the materials used in the coating are safe and non-toxic.

Lifesaver
I had one years ago and burned it out, it worked great, it was so nice to have a hot cup of coffee consistently. Flash forward to a few months ago and we were prepping for trial. I was panicking because I wouldn't have my coffee. I purchased a new mug and it was an absolute lifesaver!

Nice that it keeps coffee hot but charger stopped
It will not connect to my phone so I can't adjust the temperature and the charger stopped working. Good thing my wife has one so I can take turns with her recharging it.

Loved it
I got this as a gift and loved it. But, although it still works well, I got it in red and the colour is chipping off inside & out! Not sure if it’s still safe to use.

Never reconneted
After constantly disconnecting from my phone, I deleted the app and reinstalled it. I ensured Bluetooth was functioning properly on my phone; however, I could never get the mug to connect. The lights on the mug flashed white-green-red ... nowhere on the website is this issue accounted for and I never got the mug to connect. Very frustrating and will never buy it again.

Cold and "empty"
It works occasionally. I have to fiddle with it endlessly to get it to start warming. Then it will shut off and say the cup is empty when it's completely full. And forget about trying to heat up half a glass, that will register empty every time and there is nothing you can do about it.

Feature Request
I Love the Ember mug, I've had mine for 5 Years and it's wonderful!!!......But i have a feature request! I would love a default setting with the Health X Ember setting, so I dont have to open the app for every cup of coffee to registrere the caffeine intake, thats so annoying!
