It did have a bit of success when it came out. Quite a few bought it.
I think it works as advertised.
There was some problem apparently a few months ago with the coder pocketing money for it instead of passing it to his employer or something like that. Not sure if that was resolved. I had understood actually it was no longer available
Maybe it just disappeared off the radar.
I dont think it is 'approved' for use by Refractive now for that reason and some other conflicts over advertising but Refractive are heading toward tighter integration that does much the same thing and more with their plugins like Octane for Max.
Interesting to know how they got your email address.
Probably OK though
