The quality of this strap is good, but because the thickness of the padding is so minimal, and the concavity of the strap so shallow (it's very flat), it seems meant for people with a specific head shape. Since it is rigid with minimal padding it is also inherently bad at conforming to the shape of your head.
For me, the strap has a gap between the padding and my head at both the top and bottom. I have to sandwich a thin cushion between it and my head to feel decently secure.
I would have given it 2 stars, but i gave it 3 because it's more secure than the OEM fabric strap, and because the quality is good.
