I bought one (windrestrictor) back in may. I opted for the lighted version. you can get a non lighted from them for less $ than the one on ebay I saw. I liked the lighted up one, it lights up red and adds to alert the dumba$$'s out there when I hit the brakes. Had a similar type of thing with my bike, it would flash the brakes and oscillate the brake light mode for the ,ahem, dumba$$'s out there.
Oh yeah, the restrictor looks good no cracks or problems after 3000 top down highway miles on it.
