What do grades mean?
Grade A — Like new
Barely any cosmetic marks — closest to a fresh unit.
Grade B — Light wear
Visible signs of use. Cosmetic only — never performance.
Grade C — Visible wear
Clear scuffs or marks — the honest budget pick.
- Grades describe cosmetic condition only — every unit passes the identical bench checklist before it is listed.
