We at Laptopex focus on maintaining transparency with our customers. So we believe in maintaining grading systems to separate out different laptop models. Our dell refurbished laptops are categorized as follows: Grade A: Laptops in good cosmetic condition with very little sign of previous use. Grade B: Laptops with a moderate visual condition, lower than that of Grade A with slight dents or scratches at a cheaper cost. Both the Grade A and B refurbished laptops have similar functional conditions.
