Ember customer service sucks. They don't care, they are like weird robots who just tell you to keep warm. Yet another coaster pin issue and they have promised for 6 weeks to send another. They are as low as a company could get. I wouldn't ever buy this trash again.

As other reviewers have said, it is pointless having this mug as it never remains connected to the app so every time you try and use it you have to go through the whole searching and pairing process, which inevitably fails. This is not a short term problem. I have had the mug for over 6 months and nothing has improved despite thousands of reviews which state the same issue. I have many other devices connected via Bluetooth and never had a connection problem. The only way to effectively use it is to get it set and forget about the app. This means you can't change the settings or preset temp.

Returned a travel mug as I wanted the base mug, they failed to provide proper return details and have sat on the refund for a few days now

It's nice coffee mug with a warming plate. If you're purchasing it to be able to use the app to keep it hot off the plate, especially if you have an Android device, do not purchase this product. Even the Ember website shows that they haven't done product testing on newer Android phones. I would understand if this were a brand new item but it's been sold for years at this point. And at a cost of $150, the customer should be able to expect a product that works as promised. Ember does not work as promised.

I have had the common issue with one of the pins on the coaster staying depressed so it won’t charge the mug. A real design flaw and great shame as I will miss this mug.

The app is an abomination. The fact that there are no physical buttons (on the base for example) mean that I have to adjust the temp from the app but it never connects. No good excuse for this at this price point.

I want this to work SO bad. So bad, that I've purchased 3, thinking they'd eventually get it right (first purchase was when the company was new) Alas, they still haven't fixed the mug's issues - inconsistent charging, inconsistent connection with app, hit and miss ability to keep coffee warm. I am so sad, I give up. A pin on the charger is (once again) stuck in a down position/not charging. No more requesting a new charging base. I am done. :(

After a few months the mug stopped charging because a pin on the charger was bent — a common problem as far as I can tell. When I contacted Ember I found myself in a doom loop of robo-emails asking it I was happy with the service, but not a single one providing a solution or even acknowledging what the problem was.
