“The screws in the pack were only long enough to pass through the mounting plate - nothing else!. They needed to be able to pass through the mounting plate, the camera or RPi board, and a nut.
A spacer would have been handy so that the circuit boards are not tightened onto the mounting plate, putting stress on the soldered joints of exposed components.
I have had to source from longer screws and spacers from elsewhere.
So the only value this product had was a piece of shaped acrylic.
This is a badly thought-out product.”
