How we field-test
From crate to verdict
- 01
Run it past spec
Claimed range, torque, payload and build numbers get checked against what the unit actually does before we write a word.
- 02
Check it against the field
Published range, torque and payload weighed against teardowns, owner reports and warranty threads — the mileage other people already put on it.
- 03
Log the failure points
Where it slipped, overheated, rattled loose or fell short of spec goes in the write-up. Affiliate links are flagged; they never edit the verdict.
Spec sheets lie sometimes.
Mileage doesn’t.
