IMO When windshield wet I doubt it going to scratch the plexiglass with little amount of pressure the wiper applies. These kits has been around for while. Basically drill required size hole and assemble it. Nice option especially at night when lights and rain create bad glare if water don’t bead off. I don’t drive my cart at night hardly at all so don’t need. I slow down in rain so I can see better, a new concept down here.
