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.
"Excellent" Grade - Monitors
"Excellent" grade is reserved for units that show evidence of very little to no previous use. Any wear on an "Excellent" Display, including housing/frame and/or external surfaces (i.e. Frame) is associated with standard minimal use. "Excellent" units may have minor scuffing and / or minor abrasions on plastics with from standard light previous use."Excellent" Displays will feature no scratches, cracks, chips, dead pixels, dark spots, discoloration or blemishes. Units will only feature the standard minimal wear and tear that is associated with a used unit.
"Good" Grade - Laptops
"Good" laptops may feature one or several small dings or dents on covers and / or small paint chips on the surface or small hairline cracks in the bezel. Laptop screens may feature uneven light diffusion in screen and may feature subtle blemishes. "Good" Laptops will not feature cracks screens but may feature slight scratching, dead pixels or white spots on the screen.
"Good" Grade - Desktops
"Good" grade desktops may have light scratches on external body and may feature more excessive unit housing and/or external case wear than "Excellent" units, including wear on case / lid. "Good" PCs may feature one or several small dings or dents on covers and / or small paint chips on the surface.
"Good" Grade - Monitors
Displays in the "Good" grade have been fully tested and are functional but may include scratches on body, small paint chips, minor cracks on body, loose and/or wobbly bases. "Good" Display screens may feature uneven light diffusion in screen and may feature subtle to moderate blemishes.
