I just put a set on so I don't have enough data to comment. I'm sure that after my cross-country drive starting in a week I'll likely have something to comment on! Installation was easy. Oddly, there didn't appear to be any clip on my wiper arm to remove. I just took the old, stock blade off and put the new one on the driver's side and it worked perfectly, cleaning off a lot of crud the first time I used it.
