Neither Grade Is Refurbished

Both Flawless Pre-owned and Grade A drones are sold in original condition. We do not restore, repaint, or swap parts on pre-owned units. "Refurbished" implies cosmetic or technical restoration - our pre-owned drones are graded and sold as-found, assessed by MOHRSS Level 3 certified technicians.

40-Point Inspection

Every pre-owned drone undergoes a 40-point inspection across 5 categories (Structure, Battery, Flight Systems, Imaging, Communication & Software) by MOHRSS Level 3 certified technicians before grading. View the full 40-point checklist.
