Bucking the trend - I am impressed with the wipers on mine - much better and certainly much quieter than my f34.

One of the things that could affect performance is not cleaning the windscreen properly after washing the car - any shampoo/wax product will leave deposits on the windscreen. I use a concentrated household window cleaner - the consistency of water, not the cream stuff - on a cloth on mine, works a treat both inside and out.
