I've got the Ventureshield protector. I'd recommend it but with reservations. On my Tornado Red, there is a slight colour difference after 2 years on and there is a white line across the middle of the bonnet that I can't remove and it drives me mad the number of people that tell me I've got a big scratch on front of my car.
On the plus side, I have no stone chips at all on the front

, just a couple higher up, nearer the windscreen.
