Refurbished Computers - Cosmetic Grading Guide
Our supplier's refurbished hardware is typically graded either "Excellent" or "Good", however, some legacy products were graded under a letter grading system (A, B, C). Please find the definitions for each grade below and contact us if you're uncertain of a device's grade.
Used Smartphone / Refurbished Mobile Phones
"Excellent" Grade
Devices in this category appear like new, with very minor wear. Expect light or fine scratches on the screen that are shallow enough not to catch on a fingernail. The edge around the glass is virtually flawless, save for possible light scratching around the power port. The back plate may show light/fine scratches, including on the Apple logo, with any discoloration being minimal.
"Good" Grade
These devices are characterized by being fully tested and functional even if they have body scratches, minor paint chips, or a small hairline crack on the screen. Screens are free from dead pixels but may exhibit slight scratching from moderate use.
Refurbished Desktops, Laptops and Monitors
"Excellent" Grade - Laptops
Reserved for units that show barely any signs of previous use, these laptops may exhibit very minor scuffing or abrasions, associated only with minimal standard use. The keyboards show light wear, and importantly, the screens are pristine, free from any scratches, cracks, chips, dead pixels, dark spots, discoloration, or blemishes.
"Excellent" Grade - Desktops
Desktop PCs in the "Excellent" grade category are free from deep scratches, cracks, paint chips, or any broken/missing pieces, ensuring a sleek and almost-new aesthetic.
