Ember Temperature Control Coffee Mug 10 Ounce

This mug has been tested and is fully functional. It has been factory reset and is ready to be paired with a new device. Simply install the app on your phone and follow the instructions to pair. I personally do not like the app. It tends to crash or freeze, but once you are paired and have set your desired temperature, there is no longer any need for the app. The mug retains memory of the previous setting. Ther is some light wear such as scuffs and scratches. Please see photos for details. Any questions please reach out. Thanks for looking.
