So far I have not yet worked with it, but if the screws had a firm hold at least, so that does not rotate when tightening the wing nuts this, some would be gained. The center screw for clamping the rod can be attracted effectively only with pliers. In either case, I'll have to think about something. The lateral alligator clips can not be moved on the pole; This would certainly be an advantage sometimes. I'd rather pay for something Functioning more, but there is that? For Rolson product there are currently no book reviews.
