They work as they should but the little hex nut that keeps the tip in place and used to shorten and lengthen it's reach is a huge pain in the ass to turn. Two nuts, both need to counter screw to tighten. Ever try to pick up a coin on a hard flat surface with no finger nails? It's that obnoxious. Also the rubber tip slides off the screw it's attached to and rips off, if the pressure is too much or kept on too long. I'd pass on this set.
