The revolutionary revised design has the nuts captured by the plastic housing, this removes the need to use a spanner or pliers to hold the nut while tightening the screw to secure the wire. Simply thread the wire up through the hole, wind around the screw and tighten with a screw driver.
Cheaper versions of this product do not bend back on themselves meaning the bodywire pins can touch the guard and result in a white light. This is the most common cause of intermittent failures on foils and what many miss diagnose as bounce out hits where they belive the point has bounced off a hard surface and not regestered a hit.
