Works great and looks good
on March 24, 2011
I have Thule's square bars and the fairing works as advertised, totally eliminating the howling sound from the bars without creating an additional wind noise. As others have suggested, the assembly is a little complicated; it's very doable, just don't wait until the last second because it takes some time to decipher the pictures in the assembly guide. Included with the fairing is a set of clear plastic stickers that you apply to the roof where the fairing feet touch the roof. This prevents the feet from making rub marks on your paint.
Note on roof boxes: you should remove the fairing when you use a roof box. You want the air to go under the box; the fairing and box together will trap the air, creating wind resistance. Thule doesn't mention this anywhere. Fortunately the fairing is easy to remove and reinstall. Just tilt the fairing upwards and the arms will disengage from the plastic clips. I'd leave the plastic clips on the bars as they'll probably break if you remove them.
Before you buy the fairing though I'd try the trick another reviewer suggested, where you wrap a rope or bungee cord around the front bar to eliminate the wind noise.
