Yeah, I have purchased this eBay one you show. Functionally these work great, especially since the holes line up perfectly with where they are supposed to be on the table (unlike the Peachtree one). Only complaint that I have about these is the fit. Looks like they are free hand sawn instead of a template being used. As you can see in the pic below, this ZCI doesn't track the curves and sides of the table all that well, i.e. should be a more uniform gap. Doesn't really matter though since it doesn't affect its function...just surprised that it was cut freehand instead of using a template.
