Only yesterday I opened up my packages preparing to fix these Kamatto wipers. Then, I noticed the long wiper is slight bend in the center. When I finished fixing the wiper I didn't notice any problem until I started to used it while driving in the rain. Upon thorough inspection, I noticed the center of the long wiper has an indention and while wiping it creates a visible marking in the view of my vision on the windscreen.
Do you have any warranty for my purchase? Please advise. Thank you.
