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.

Grade AExcellent

Light signs of use that are hard to see at arm's length. No scratches on the display.
