Flawless	No scratches or scuffs anywhere. Screen and body look like new. Fully working, no cracks.
Good	Light, minor scratches or scuffs from normal use, none deep. No cracks or dents. Fully working.
Fair	Heavier scratches, scuffs, or a small dent, but no cracks in the glass or screen. Fully working.
Cracked screen	Cracked or chipped screen or back glass, but it still powers on and the touchscreen works.
Broken	Powers on but has a fault, a bad display, or a part not working (camera, buttons, Face ID).
Won't power on	Won't turn on or hold a charge. We still buy it for parts.
