Review (1/5): Screws broke, making it unusable.
When I got it one of the arms was too tight so I tried to loosen it with a start it (the correct piece), but I literally just scraped off the shape of the screw. Like you know how the shape of a screw dictates what aceewbit to use for it? When I rotated the bit, the shape literally scratched off, leaving the screw just a metal bolt with a hole in it and no way to loosen or tighten it.
Also doesn't work as a comb very well.
