Well after 12 months of driving around with three 8 inch long cracks in my screen thought it was about time to get it replaced. £70 excess through the insurance, Autoglass came out this morning (bang on time) and had the new screen in within an hour. Excellent service and got a pair of new Bosch wipers to boot.
The new screen is amazing with the new wipers and for the first time ever the wipers don't smear or thud. So if your not happy with your aero fit wipers just get a new screen fitted LOL!
