I purchased these as part of a bundle and while they are fine there are some things that could be improved. With the stands, mostly fine, however the cable that attaches the safety pins to the frame is cheap and if frayed would cut you. Spend slightly more for some more flexible cable and it would be a great product. With the truss, again the metalwork is good. A nice light aluminium frame. However, the plastic clamps are not great. The frame is stiff going into them and at least one split. They do come with spares though which I think is to give you a choice of how to assemble. Can't be sure though because it came with no instructions. It also has the same gripe about the wire attaching the safety bolts being cheap, stiff and nasty.
