Why is so much cheaper than the usual ones I have seen?

has anyone tried it?

It might work but I will hate to have a cheap looking accesorie on my car.

Jay said that at least 4 people bought his windblocker. Someone must have received theirs by now and tried it.

there was
 

a write up on pete's boxster board, basically it doesn't work.

Yea, I have installed and driven with these from Jay for about a week. Here's my input. With the passenger windows down the effectiveness of the Lexan inserts is negligible. With the windows up the effect is somewhat noticable but barely. The one thing I have noticed is the inserts add some "mass" to the plastic roll-bar inserts and seem to limit the rattles a bit. I don't think the reduction in wind or noise is measurable. I will say the workmanship and product quality is fine. I think Jay is very customer oriented and a good sponsor to add to this site. I would be interested to hear any other feedback from anyone who has bought these. BTW my dealer thought they looked cool!
