I bought the slimmer self adhesive deflectors. They're good, they don't stop the window rattling but they allow you to have the window open a bit without the water from the roof coming in. I've had them on there about 4 yrs now, the instructions say not to put them on if its below 15C but it was 10C when I did mine. They're still there and they've picked up a few bits of bush during laning so that glue is pretty strong.
