Audi A7 Wind Deflectors??

Hi everyone! 
 

So I’ve not long had my Audi A7 (2011) and summer is officially over and rain seems to be a regular thing now.. Unfortunately for me the windows are frameless and whenever I open them a sheet of water likes to drop in. I quite like to vape while I drive so I have been looking at getting some wind deflectors.

My question to anyone that might be able to help is how effective are the wind deflectors for the A7? Only a handful available online and it’s a lot of money to spend on a bit of plastic.. When I open the doors the windows only drop a little bit so surely the deflectors have to be quite shallow?

Has anyone seen deflectors on an A7 and if so how well do they work and do they actually look any good?? Mines currently fully blacked out so shouldn’t be a problem shouldn’t have thought.

thanks 🙂
