Good screws and fully priced ok

Have to separate in my basement a small partition built around my "office" from the rest of the basement. Profiles I got from Horn ** ch, it had to be not in a Super Mega Quali.
In my view, these screws are to use for the "small home improvement" quite well. I'm not 100% sure what differences are there to the more expensive Knauf Drywall Screws from the hardware store, so I can hardly see a difference. But I'm also not an expert for that matter.

Anyway, I could without much trouble screw the sheetrock to the Staenderwerk, and the second casing was not a problem.
Only my bit holder with depth stop was not very high, but because the screw can be used for anything.

Full marks to the screws, thoroughly recommended!
