After looking at reviews on this, i decided to buy a few for a new lighting project.
They arrived beautifully packed - and after unboxing it felt really good and sturdy - although i was wrong.
after loading up 4 flat par cans, the stands had a tendency to lean to one side, and felt very off-balance. the security pins are barely the width of the support bar, so they are prone to be finicky and occasionally pop out.
Ended up buying trussing and tour grade stands, but they would be handy in a pinch - just dont put them anywhere they can be knocked, or near light wind
