Cosmetic Ratings - we're often asked "why is your numerical rating so low when the product looks great?" We tend to be very conservative when applying a cosmetic "rating" to products. Virtually nothing is a 10/10 unless it is nearly new and looks factory fresh. Our 8/10 is what a lot of people might call "mint".
