I wasted my money on piaa. (Not the 20-25 dollar per side ones, the aerodynamic 30-35 dollar ones).
For such excellent reviews. They were garbage. One flew off my wiper arm at 50-60mph. The problem with them (or the specific pair i bought at least) is their mounting system to your arm. They are a all in one adapter based mount. And the ones that were suppost to fit, just didnt. Ive changed MULTIPLE wipers out, (i assure you this wasnt a factor with my hands or mis-understanding of how to attach them). Eventually, i just figured that the poorly snapped in fit would end up working... Should of trusted my instinct and returned before i said "screw it" and had one fly off. I ended up w/ basic rain-x on the fronts, and the cheapest wally-world store brand one available in the rear. They work fine. And at half the price of the fancy brand. Also the replacment cheap ones i bought actually are secure to the vehicle.
