It was made by some company in Germany - a MAJOR PIECE OF JUNK.
I bought it because I though it would look cool as it covered the back seats - but there really isn't a lot of turbulence anyways - the fit was poor - pins that fit into existing holes in the interior panels, and it wasn't any more structurally sound that a screen you place in a doorway to keep a baby or pet separated.
If it was up to $50 I would've kept it but I promptly returned it.
This Ebay Listing
is the same piece of junk - do not buy.
