Grading Standards

Why Grading Matters

In the secondary electronics market, trust is built on consistency. A clearly defined grading system eliminates ambiguity — buyers know exactly what they're receiving, and sellers can price inventory accurately. Without standardised grading, disputes, returns, and reputational damage follow.

Every device in our inventory is independently tested and inspected before shipment by trained technicians following a strict, documented protocol. Our grades are assigned objectively — not commercially — so you can quote them to your customers with confidence.
