# How we test

Every unit goes through the same six checks before it ships. Any mark or defect is written in the listing and shown in the photos.

1. **GPS**: Gets a fix outdoors and records a short ride.
2. **Battery**: Charges fully and holds its charge.
3. **Screen**: No dead pixels or backlight problems.
4. **Body**: Every button works; case and mount tabs checked for cracks.
5. **Pairing**: Phone, ANT+ and Bluetooth sensors connect.
6. **Reset**: Factory reset, ready for your account.
