The advantages of the Smith are that it is absolutely silent, gives the minimum obstruction to vision, and operates as long as the car is moving. We have run an experimental car 17,000 miles fitted with one of these wipers without having any trouble; We have also run another car 10,000 miles, and another car 3000 miles without any trouble. As an alternative we would recommend the Folberth suction type. Hs.{Lord Ernest Hives - Chair} | ||
