Generally the shutters work well. I was able to get all sorts of four sided shapes. Movement of the blades does get limited by the configuration of the snoot itself. So movement of the blades is not completely unlimited.
I was thrilled when I found out that Strobepro was also launching a snoot. Ordered it right away, arrived within a few days and the product is super solid. Does not heat up too much (I shoot strobes mostly, not too much constant light). The gobos are great too. The framing shutter is as well... 10/10
The only thing that could be improved is to include a link to the YT videos on how to set this up. AND, of course, to have some sort of bag/ backpack/ to fit all the tools in conveniently.
