Also be aware I also had previously added batwing wind deflectors I found on Ebay that helped block the air coming from under the wing. The combination of the two works pretty well.
I have a Puig deflector also but haven’t put it on yet. I have the widest version.
I have installed mine, which is the small one, on three windshields. So far, no slippage or looseness even at Interstate Hwy speeds. No marks on windshields that are not superficial and are removed by clear plexiglass cleaner. It goes without saying, please make sure it is centered and the clamps fully seated against the edge of your windshield before tightening the clamps. You will of course need to try different angles of the deflector to see what works best for your situation. I am average height at 5' 10" and what you see in the photo seems best for me. Hope it works out for you as well.
I’ve got them on my bike. Seems to be an improvement but haven’t done many miles in many conditions with them yet.
