I love these things. So easy to use and so durable. You really have to be careful when screwing in the screw. DO NOT overtighten. It will tear drywall. You want it tight and it is! I used it to set up my Rubbermaid closet (in places I wouldn't hit a bolt). They are really durable. I would definitely buy them again. I haven't checked the prices from local retailers so I can't comment on the price but felt it was reasonable for the quantity.
