Yes. I found it much more effective than a higher screen even though the high screen is exactly the same height as the stock screen plus spoiler. I reckon because the spoiler lets a little air to pass behind it there is less negative pressure and as a result, less turbulence.

The interesting thing is, I'm getting rid of it because I've fitted a TT high seat which has altered my position in relation to the screen/spoiler. This is why I'm going to make something that I can tailor to my exact needs. The spoiler worked brilliantly till I raised the seat.

I am 1.80m tall BTW.
