Review on High-Performance 12-Volt Marine Windshield Wiper 🌊 Kit with 2.5-Inch Shaft and 80-Degree Sweep by Todd Hauff

Bad design. If you do not install the nut on the back when installing, the outer bolt will move away from the wiper shaft when tightened. Good luck finding a soft thread nut. Also, when tightening the wiper arm on the pivot pin, there is not enough tightening to keep the wiper arm moving at all. You'll need to take out your Dremel 3000 tool to grind the tip so that the grooves in the wiper mount hook into it. I would not recommend this product unless you want to do that extra work. You would think they wouldn't cut this design.
