Pretty good, I like these over the nail-in versions.  Used them for cable and for low-voltage CL2 #14/2 (speaker) wire.  A couple actually had no point on the screw, but cost of 1-2 defects is nothing compared to the price locally.  I did not have any issues with plastic breaking as I have had with others in the past.  They install nicely with a hex drive bit in a powered screwdriver/drill
