These straps are just what I needed to secure my expensive SxS. The lock on the hook makes it much easier to assemble the car yourself. The ratchet itself is sturdy and easy to use for both tightening and loosening. The straps are also well made and seem to last a long time. First use was on a 300 mile one way trip so I'm very happy with the seat belts for the first 600 miles and should work fine over a long period of time.
