Has anyone ever used one . I bumped into an old guy today who works one of the estates in work. Anyone not seen him for a few months and he shows me his slx.which is remote control and no clamps. He let me have a go , I couldn't believe how much easier it is.what he's done is fitted a small switch with a battery to the bottom of his pole , and put what looks like a small pulley and wire inside the pole.and removed the clamps .hes been using it 6 months with no probs . He let me have a little play with it .the pole stops exactly were you want .come on all you wfp suppliers get on the case . I defo want one . Cheers barry
