Well... okay for the cheap price...
Fast and good delivery, as usual from SVB.
I use the product to attach my flag lines to the upper shroud.
A screw is used to press a (very) small metal strip on the back of the plastic cleat against the steel cable and is supposed to clamp it in place. When I screwed it on for the first time, the metal strip was bent so much after a few turns of the screw that it fell out (luckily it landed on deck and not in the water ;-)). I then straightened the metal strip using pliers and reinserted it. This time I only tightened the screw very slightly. The whole thing doesn't feel particularly stable, but at least it's been holding for a few weeks and has already withstood some strong winds on the North Sea. I might glue the screw and metal strip together again with epoxy in winter storage...
