The only negative is that for 90 ° hooks, the image is too deep, so that the leno necessarily leaves its mark on the wall at full reindrehen. That is, just at the end of the pure rotation, when it comes the most difficult, and certainly again pliers is needed if the point around the hook visible / should remain clean later. In the crook screws you have not the problem.
The handle is great if it is too stiff for the cordless drill or the hook must be precisely aligned.
Processing seems fine, but so far only one application.
