Understanding Cosmetic Grades

Reboot IT categorises refurbished workstations into two transparent cosmetic grades. Excellent grade units exhibit minimal signs of previous use with barely noticeable wear, offering a near-new appearance ideal for professional or client-facing environments. Good grade units remain fully functional with more visible cosmetic wear such as light scratches or minor scuffs, delivering identical performance at maximum value for users prioritising function over aesthetics. Regardless of cosmetic grade, all devices receive identical rigorous testing protocols and deliver the same reliable performance—only the external appearance differs.
