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 monitors are for those who expect a display showing very little to no signs of previous use. With minimal scuffing or abrasions on the housing/frame and no imperfections on the screen, these units offer an almost-new viewing experience.
"Good" Grade - Laptops
"Good" grade laptops are fully functional but come with signs of more extensive use compared to Excellent grade units. This includes scratches on the laptop body, heavier wear on keyboards, and possible small dents or paint chips. Screens may show uneven light diffusion and subtle blemishes but no cracks.
"Good" Grade - Desktops
Similar to laptops, "Good" grade desktops may exhibit light scratches and more noticeable wear on the case compared to "Excellent" grade PCs. Small dings or paint chips might be present but do not affect functionality.
"Good" Grade - Monitors
Displays in the "Good" grade have been fully tested and are functional but may include body scratches, minor cracks, or a loose/wobbly base. Screens could display uneven light diffusion and moderate blemishes but remain free from cracks.
