It can be difficult to get it lined up right and ratchet it tight without feeling like I'm about to screw up my truck bed, but it's easy enough to sort out and holds well. Having two people does make it easier/quicker. I haven't used it with anything really big or heavy yet and I don't drive like Sheriff Rosco is chasing me, but so far it does a good job keeping stuff in place. There's even a hook you can hang a bag or something onto. I'm guessing that's what it's for anyway. It ratchets and releases simply enough, but I can see how it could nick or pinch yourself if you're going too fast or something. I still have time to get injured though. It also sits nicely behind my back seat. It seems solid and well built overall, but I don't use it on a daily basis or usually need it to hold big/heavy stuff. I suspect for my use it will hold up fine... your mileage may vary.
