Ember 14oz Mug 2 Temperature Control Smart Mug Sandstone

Didn't even last past 1 year. Battery was just ok from the beginning, but deteriorated within less than a year and had to get a new charger within the 1-year warranty period. New charger was even worse, barely lasted a few months. Was really great while it lasted, but after that, it's completely unusable without the charger.

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

Charging Pin Stuck, doesn´t charge, what a waste of money buying this.

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.

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.

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.

I bought my Ember mug 4 years ago and it still works perfectly. I use it every day. Love it so much!

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!

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.

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.

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.

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.

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!

I received the Ember as a birthday present in late September, and it’s now 10/29 — I’ve barely had it a month, and it’s already broken. I followed all the instructions carefully: hand washing only, keeping the coils dry, etc. Despite that, it won’t heat up or sense any liquid in my cup. I really wanted to love this, especially as a newly postpartum parent who relies on coffee, but every day I end up transferring my drink to a microwave-safe mug. Don’t waste your money — this is an overhyped luxury product that’s more trouble than it’s worth. Nothing will ever beat just a classic mug.

I have purchased SIX total: personal use and as gifts. Pricey, but friends and family will love you for it! I will NEVER be without it! A MUST if you enjoy your coffee HOT with EVERY sip.

The cup has a couple major issues. 1) the app frequently disconnects from the cup. You have no idea how irritating it is to constantly need to set it it up again when you just woke up. 2) battery doesn’t last long. It must be charged every day. 3) the cup is plastic. Nobody likes a plastic mug.

The cups are nice. They work well. They don’t stay charged all that long but they get the job done. But… the charging plate has a little super cheap circuit board in it which hold the contacts for charging. They don’t last! So after buying 3 cups… they are now just that….. cups!

Not a cheap product, but there is nothing else quite like it on the market, at least that I know of, and you get what you pay for. This product is near perfect for what is does. I tried the old “hot plate” models from the past and they just burn the coffee. This does exactly what it says it will do: keep your coffee at the temperature you select, and it does it very well. I have not had any issues with the charge plate as some have, but I suspect that strongly correlates to your water hardness. “Steve” is indeed a hero not only for having an engineers mind, and so a strong desire to figure out what the problem is, but also a desire to help others by publishing his discovery. Yea Steve! I would suggest always drying the bottom of the cup when cleaning, when you first put it on the charger you’ve probably noticed a ring of condensate from the cup: this is the water in between the rubber rings being “steamed” out by the heat the battery makes as it charges, so the dryer the better. Lastly, you really need the lid they make for this, ideally it would be included with all models. If you take cream in your coffee (like me) it’s simply required, otherwise you’ll get “milk skin” on the surface which is not good. And for every user it will at least DOUBLE the length of the battery time. Ember describes this quite clearly in their description of the lid, take them at their word. Buy with the lid and keep an eye on the charging pins and you’ll not regret it; excellent product overall!

This was a wonderful gift that keeps my beverages hot at my work desk all day...Love it...

I have mix feelings about this mug. When I received it was truly happy with it, nice to always have a cup of warm coffee. The app could use improvement but it's not that mad to make me not want to use my mug. The issue I have with it is the coating inside started to peel. Considering the price of the mug I would expect it to last a lot longer. I also had to have the coaster replace because the pins weren't working and thus not making contact to charge. If you're looking for a long term mug I don't believe this is for you. If they price doesn't hurt you and willing to have to buy another one in a few years go for it, you'll love it.
