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.
