Very easy to use, install etc I used to make tons of these drywall screws (other brands). It was no different. However, the plastic used in it is of extremely poor quality. I used two to pass the cornice and one had its head fall off and the other when I tried to drive a screw in it broke almost immediately. opportunity (it's plastic...). But I didn't. The plastic used in it is much cheaper than the plastic used in models from other well-known brands.
