Has anyone had any experience with Cavision .9 or 1.2 Grad ND Glass Filters such as the one on this link:

I know that Cokin Z Pro can take 4x4 (100mm x 100mm) filters and I believe it can be adjusted to accomodate the filter's 4mm thickness. I'm tired of resin filters that can be easily scratched but I don't know if glass filters are also susceptible to scratches. Am I better off buying the Tiffen or Formatt brands?
Thanks in advance.
