Review on KEEPER 5105 10ft Cam Buckle Tie-Down, 300 lbs. Working Load Limit (900 lbs. Break Strength), 4 Pack, i-Pack by Elvis Kimbro

These things work great. They survived an 11,000 mile trip across the US while keeping a padded roof bag strapped tightly to my car. The hooks fit well under the wheel rim at the rear. Attaching them elsewhere wasn't as easy, and while the hooks are fairly versatile, they can slip off even when rubberized. The textured surface of the hooks could be better. Still, there is a small downside. The only other issue was that after many tightening/loosening cycles (60 days or so) one of them started to wear out a bit. This was mainly because the tensioning angle was not quite parallel to the tensioning mechanism, allowing the strap to snag on its edge. Not exactly a bad design, just something to watch out for. Overall, they did very well in a demanding and heavily used situation, and I expect they'll get a lot more use out of them.
