The cams are held in place by bolts going through the middle to nuts. When I received mine, all 4 nuts had come off and the internal springs that make the cam open/close, had popped loose. I had to struggle to get everything back in place. Once together the cams performed as designed. The manufacturer should have place a piece of tape over each nut to keep things in place during shipping. I deducted 2 stars for the frustration of having to reassemble everything before use, otherwise I would have given 5.

These were well built and as described but I didn't measure for what I wanted. I intended to use them on my Hobie Cat to hold a small line. These were too big. But they worked very well on another sailboat to hold some bungie lines that control the keel. I screwed and glued them in place and they are doing the job quite nicely. I like the combination of quick release and sturdy hold.

These clips work as expected. I mounted them on my fishing kayak. I did have a problem while mounting. I let one side slip and it came apart and spring sprung out. Haven’t figured out how to get it back together.

It is what it is and works well. So far appears to be of good durable quality

It did not hold the 2 to 3mm diameter cord I was using had to buy the more expensive Harken Cleat that worked perfectly.
