Charging coaster will fail
I love the mug and use it all day, everyday. Unfortunately I've had three and the charging coaster has quit working on all three. It is always the same issue. The mug is useless because it won't charge.

Save your money! The charger doesn’t last…
The cup is fine. The charging coaster only lasts a few months. I’ve had two, and both have stopped working (with the same issue). I don’t know how the ratings are so high. A quick internet search reveals that this a very widespread issue.

Planned obsolescence isn't a good business model.
This is the second ember mug I've owned. the first was a 14oz mug that lasted about a year and a half till the coating on the bottom started to peel off. This time around I purchased a 10oz mug. This one lasted a year and 8 months seemingly because I switched to wooden spoons so as not to scratch the mug. still peeled off. these mugs cost way to much to have to replace every year and a half or so. I've contacted ember and all they'll do is offer a discount on a replacement since their warranty is only for a year. Likeeise the mug has issues telling if it's got liquid in it or not and will just turn off randomly. No updates or reseting will correct this issue long term. If you must get a ember, get the travel mug. It actually stays on and the interior is stainless steel so it shouldn't peel off after a year and a half. plus you can adjust the temperature without the phone app.

Pretty good. But cost is for a 'great' product.
Call it 3.5 stars maybe. I am still using it a few years after it was gifted to me, and like it for its purpose. Pros: • Keep consistent temperature very well. • Nice fit and finish, good construction. • Battery lasts a respectable amount of time. Cons: • The charger-to-mug connection is two spring-loaded metal pins. One of these failed on my first charging puck, so I had to buy a replacement. Two issues: the spring can fail, so your mug doesn't charge (my issue), and since they're solid, physical contacts, it's theoretically possible to short them out with a spill or sufficient condensation (I typically wiped any condensation off mine regularly to avoid this). Other charging setups for modern devices that may get wet typically have electromagnetic transfer. • Cost is up there considering the cons and the competition (which I won't name).

Too hot for me wish it had lower settings than 120
My husband won this at work. It’s fine if you like extremely hot coffee, but I prefer mine hot without being scorching, as I have a sensitive palate. I wish it offered lower heat settings than 120°F. If it kept a consistent 100 or even 110 it would be perfect!

Short Lifespan
I received my mug as a Christmas gift. Loved it so much that I bought one for my husband. Enjoy having perfect temp coffee to the last drop. HOWEVER, they no longer charge. Tried all the hints, tricks and hacks to nudge them into charging without success. Sad that they oi longer work. Short life given that they were gently cared for.

Poor Design
I got my mug for Christmas 2024, and I really like it. However, the charging disc quit working after 4 months due to a design or quality flaw. Ember replaced it for free, but the second one has now quit working for the same reason. I know 2 other people with Ember mugs, and they have had the same issue. I don’t recommend this product. At least not until they fix the issue with the charging disc. The product is too expensive to have this serious of a flaw

Horrible product
I won this mug at work so I was taxed on the value. It worked for a few months and now it doesn’t charge. I come into the office after it has supposedly been charging all night, open my app and it says “empty” and to charge it. For as much as these things cost, they really should work for much longer than a few months

Poor battery
I own the large mug. It doesn’t hold a charge past one cup of coffee. Even after charging overnight. It’s not a year old.

Skepticle
I loved this mug at first. But after some years the ceramic coating inside started to peel. For something of this price I would have liked for the mug to last longer.
