Quick install.  Directions a bit wonky, but figured it out.  LOVE the fabric...almost like a woven netting which is then backed with a fine fabric.  Tracks glide very easily. And has just the right amount of room darkening...not black out, but shading.  What’s great about the design is if you get tired of the color of the  panels (or if your cats decide they really like the woven netting as a scratch post...which I know will happen), you can change it out  with a fabric of your choice and remount just the panels...the track still stays in place.
