The Ember mug is highly appreciated for its ability to keep beverages warm for extended periods, making it a favorite among coffee lovers. However, many guests have expressed concerns about the durability of the charging coasters, which often fail due to design flaws. Despite these issues, the mug's functionality and the convenience of having multiple charging stations are highlighted as significant benefits, enhancing the overall experience for users.

Good Mug / Bad Charger
I loved the mug while it functioned. But, at barely a year old, the coaster is not working. One charging pin is worn and doesn't make contact with the cup. Very disappointing.

Seemed like a good idea
I did have a charging coaster where one of the pins broke. It seems like a good idea to have an extra. Can also use it in my office

Charging coaster - a weak point
The charging coaster is a weak point from my view. I received the Ember cup as a gift and have enjoyed it. I am now needing to buy my second replacement coaster. The pins in the base stop connecting and seem to get stuck in the base and stop extending out enough to charge. I am presently deciding if it is worth it to invest in another charging coaster

Not cost effective
I love my Ember cup but this is the third charging coaster that I've purchased ($120 total). Have there been any improvements in regard to this problem? I want to keep using my Ember cup but may have to look for alternatives if this coaster malfunctions.

Charging Saucer pins are the Fault to the Mug
I’ve bought my wife three of these mugs over the years. Love the mug, however the charging saucer’s two pins are a not a very durable solution. I’ve probably replaced the saucer 5 times and I’m in need of another one if I want to continue using the mug. That’s what brought me to your site.

Don’t get the black charge plate
My wife and I both received a charge plate 1 1/2 week ago for our birthdays. Mine was the black charge plate which takes quite a bit longer to charge in comparison to my wife’s white charge plate.

Cool product, bad design...
Charging pins will fail and you are stuck having to buy a new puck. I've gone through many of these over the years and have spent more on charging coasters than on the mugs themselves. You're left with an expensive coffee mug when this happens.

Love the mug, but the charging base has flaws
Love the mug, but this will be the 3rd charging base that I’ve needed to get because the pins on the first 2 were defective. Getting the first 2 replaced by Ember was a big deal, as I had to submit photos etc on what the problem was…i don’t think they believed me. In reading many reviews online, I see I’m not the only one with this problem. I’m gonna purchase this one, as I don’t want to pitch the mug in the trash because it was a gift.

Pins fail too often
Lots of reports of failed pins. One of my coster's pin got stuck, the other coaster pin actually sheered off. Plan to replace them annually.

Good idea but poor execution
The mug works fine but there are issues. First off, the selection button is on the bottom of the mug, just a stupid location. It also shuts off randomly and is not intuitive. A simple on-off button on the side would be preferable. The second issue is significant, the charging coaster will stop working after a few weeks or months as it's a terrible design. There are two pins that must contact the mug in order to charge it, but these become stuck and eventually will not allow the mug to charge. You can clean them, but they are very delicate and poorly made so they will fail.

Terrible Design Fail
I have bought 3 and all of them have failed. I just purchased a new one in the last 2 months and it failed again.
