“It is very handy for mounting a pi but the supplied nylon screws are cheap and nasty, they stripped the threads as soon as I tried to tighten the pi to it. No I didn't overtighten.”
“Great for the price, and for the range of cases it's compatible with. My only complaint is that it's hard to tighten the nuts and bolts. They're a bit wobbly, but not like they're going to fall out or anything!”
