While the instructions aren't great, they're not really needed for something this simple. Just note that for what you're buying, the overlap is 2 inches (aka a screw). Overall it is well made and sells well. The only potential problem is that they only include enough wing nuts for each end of the trim. I add nuts at the overlaps, this will also help reduce the stress on the vinyl.
