i bought these, but i didn't do the 5 min dry wipe routine. all i did was wipe the windshield with the little wet wipe that came with the wipers. not sure if that affected how they are performing. they are fine wipers, however i notice they "flick" little splashes on the downstroke, which is mildly annoying. the moisture wicking ability is very good. overall though, i don't think they're worth the extra money over bosch icons or whatever is OEM.
