Cosmetic Grading Standards

For networking equipment like the SG300-28MP, cosmetic grading reflects only external appearance whilst performance remains identical across all grades. Excellent Grade units show minimal signs of previous use with only minor scuffing or abrasions, no deep scratches, cracks, paint chips, or broken/missing pieces. Good Grade units are fully tested and functional but may feature light scratches on external housing, more excessive case wear, small dings or dents, or small paint chips. Both grades deliver the same reliable network performance and undergo identical testing protocols.
