I use the Bosch aero & I'm quite happy with them, with one proviso; the wiper leaves the screen at the left hand extremity & wafts aimlessly about until its return journey takes it back into contact again. The recommend size is 20" as per the Europart ad', next time I buy I'll go for a 20" for the RHS & an 18" for the left. I'd measures up the discrepancy before deciding the length, obviously.
