Launched in 2014, Ember used temperature control technology to keep hot beverages at your desired temperature.
However, the product had issues:
- The app and bluetooth connection can be finnicky.
- The charging coaster uses live pins that contact the bottom of the mug. These pins will get stuck and the coaster no longer works. If something metal falls on the pins it can spark.
- The battery in mug is non-replaceable and if it fails, the mug has to be replaced.
- The battery will not charge while it is keeping your drink hot – mug has to be empty or manually turned off in the app for the battery to charge.
