The EON is the best dash cam for your car. It allows you to help self driving cars, record your drives, and unlike phones running Chffr in the summer the EON won't overheat with an included built in heatsink and fan to help keep it cool

  • Your iPhone or Android phone can run Chffr but the EON can run ChffrPlus.

You can buy one here
