Review on Cirlife Stainless Picture Hollow Wall Drywall Kit: Ultimate Solution for Secure and Seamless Hanging by Lance Levatte

I have used several wall plugs and screws from this set and so far the screws have not rusted. So why 3 stars? I doubt the screws are actually stainless steel, I messed up the heads on some when I had to screw them into wood despite pre-drilling (it was just the right size)! They seem almost as brittle as brass screws and not nearly as strong as machine screws, deck screws, drywall screws.
