I bought some Bosch o/e ones, useless in rain just streaked and at night was awful.
Got the ebay aero ones, drivers one comes with a aerofoil to keep it pressed down.
Great result, clears the screen, even dead flies get cleaned away, not just left in a yellow streak!!!
Only cost a few ££££ delivered, so impressed got some for our Punto as well.
Would not go back to the o/e ones.
