The plastic is fairly brittle,
This review is from: GoPro Head Strap Mount (Camera)
The strap is very adjustable and fits a range of helmet sizes. The problem I found was that after a couple of uses the plastic broke when I was screwing up my camera into the attachment. The plastic seems very brittle and broke under very little pressure when I tightened the screw. Not designed to last I don't think.
