So my OEM wipers that came with the car were all fine and good. after they wore out, i bought rain x wipers and found them to leave me streaks (on the left wiper) & skipping (on the smaller, right wiper). so i bought a different brand, but same thing happened: the left gives me streaks; the right gives me skipping (and boy, is the skipping LOUD). and yes, i did follow the correct size as listed in the manual: 24, 14 inches.

so what gives? is it the brand that's bad? or am i missing something?

EDIT: and fwiw, i did try multiple times using the wiper fluid to 'smoothen' it up. no dice.
and (as we expect) the heavier the rain, the less skipping there is. but the streaks still continue.
