Got a real pet peeve about noisy wipers. Just replaced the Valeo wipers with Bosch Aerotwin and they are juddery and streaky.

Anyone got any suggestions for different brands? L494 3.0L SDV6 Autobiography MY20 in Eiger Grey (Current)

Bosch Aerotwin are the very best wipers you can buy.
So the problem isn't the wipers, it's your screen.

Probably tree sap or some other issue. I usually get a piece of kitchen role, pour some washing up liquid on it and blather the screen. Then use the wipers to clear it.
Usually does the trick.
(I'm also really fussy about the blades and replace the moment I see a problem - I buy Bosch Aerotwin - won't touch anything else).

I'll give it s shot before trying another brand then, thanks  L494 3.0L SDV6 Autobiography MY20 in Eiger Grey (Current)

I fitted Bosch Aerotwin, binned them after a couple of week as noisy and juddery, nothing to do with the screen as was on a brand new screen just fitted, fitted some michelin stealth blades and not a peep out of them.

Bosch aero blades here, work well, no noise, no juddering. 2012 SDV6 - it's missing a couple of cylinders
2008 TDV8 - it was a labour of love and is much missed
