I love mine. I got the ones for the rails and the side-clips too. The side clips are especially nice, as instead of pulling two spots on the side, it pulls 12 inches at the same time, no decreases the 'waves' I was getting. Like others, I found the rail loaders very hard to use at first as they were stiff and it took a lot of hand strength to snap them on. But now they snap on easily but still hold everything tight. Don't remember what I paid for them since I originally got them 2 or 3 years ago.
