Two of these, plus a few nuts and bolts, and a piece of wood, and you can make yourself a bike rack for way less than any car bike rack on the market today.  Just bought two of these, a common pine board 10" wide, cut to the width of our truck bed, mount these to the board, then attach to the truck with a few bolts and voila...bike rack!  What I love about these fork mounts is that it tucks the bikes below the top of the truck roof, so we keep the bikes out of the wind and elements.  Also much better for the aerodynamics of the vehicle.  If you own a truck, it's the cheapest and best way to make a bike rack.

The item itself is very nicely thick aluminum.  I've had no issues with the closure mechanism, and the ones we received had a short piece of webbing on the QR to help open it up.  As far as other reviewers talking about the locking aspect being useless, it is true that one can theoretically unscrew the opposite side of the mount and remove the bike, but there is some kind of bushing or o-ring which makes that side more difficult to turn, even when free.  Plus, when properly tightened, the tension makes the smooth nut very hard to turn.  I guess if a thief had a pair of vice grips they could open it up, but I don't think the intent of this is to lock your bike up in the worst part of town and leave it overnight.  If you are driving somewhere and need to make a pit stop, the lock is enough of a deterrent for those 5-minute scenarios.  I think this is a great product, and makes the cheapest, best bike rack.
