I bought two nice NAPA wiper blades last month. I noticed that one did not click into the slot well but the other did.

Of course, the first time I fire them up, one promptly falls off. I stick it back on and it again doesn't click in marvelously, but it works.

Last weekend, I decided I'd better check them. Sure enough, the one that never clicked in well is completely off the wiper arm, and the other that did click in well is still on the arm, but the plastic guts are gone and it's hanging by a thread.

NAPA says, "Not our fault."

To anyone who has experience in this: Do you think I need new wiper arms? Or, should I go to something else, like Walmart or similar. I've heard bad stuff about the Bosch wiper blades.
