You have to hear the audible click in the 2nd picture

This review is for Bosch Evolution 4822 Wiper Blade - 22" (Pack of 1) for 2003 GMC Envoy front wipers. I was concerned with all the negative reviews but mine installed OK, hasn't fallen off yet and completely wipes clean. Instructions are bad. My Envoy has the simple hook design but the instructions indicate it requires "M2" adaptor. Well it didn't. At least the installation pictures are correct. You really have to read between the lines (pictures?). In the 2nd picture you have to snap the hook into the receiver until you hear an audible click (the double arcs depicted in the picture). This audible click is maybe 3/16" to 1/4" after you think it's already properly seated.
