Windshield wiper angle finder

Tired of those noisy and shaky windshield wipers?
Try tunning the correct angle before buying new ones!

Just remove the wiper and install the main body of the measurer, second, install the scale and for last, install the arrow.

Just rest the windshield wiper arm on the glass and you will be able to measure the angle. If it is incorrect, just give a little twist and install again the wiper!

Also, measure the pressure of the arms with a kitchen scale.
Manufacturers indicate 1,7 grams per mm (length) on the slim blades and 1,4 grams per mm (length) on the conventional blades.

Any doubts, watch this video (note that the original tool points the oposite way that this 3D model does, but it measures the same angles)

NEVER turn your windshield wipers on with this device installed. It WILL damage your windshield!
