The Cell Zone grading standard.
Grades only help if they're consistent. Every device passes the same inspection and is graded against the same written criteria, so a Grade B in one order looks like a Grade B in the next.
Five conditions, clearly defined.
Choose a grade to see the wear it allows. Cosmetic grade never affects function: every device we sell works as it should.
