Review on Upgrade Your Car'S Visibility With TRICO Gold® Wiper Blades - Pack Of 2 28 & 13 Inches (18-2813), Easy DIY Install by Eric Currie

First, the blades work well. But i have a question. Why is it that there isn’t a generic wiper blade connection? Windshield wipers were invented 120 years ago! So you buy expensive OEM blades or you need to buy blades that come with adapter kits to connect to the specific wiper arm that your car maker has chosen. No criticism of these Trico blades which come with sparse picture instructions to switch the adapter to fit your car. A minute of fiddling and you’re done. But the question remains… why no generic attachment after 120 years?
