Sin far more professional than the so-called "big" manufacturers that look like they have websites designed in the 1990s.
For sure, Fancy Steel site looks way better than Neosteel (Reminds me of early day websites) and My-Steel (It seriously has Boostrap but still poor implementation. Need huge revamp on design!) websites. Honestly I view Fancy Steel do more experimental approach when it comes to its products than other chastity belt manufacturers.
I view their films as kind of promotional films to lead to sale of chastity belts than just a porn. I think they want to demonstrate kinky use, yet popular way of use of chastity belts on its videos. It is nothing different with a movie, all people on videos are very likely to be actors (They even link actors' social media links sometimes). For certain, I never want to be affiliated / associated with them at all, though.
I see all the time fancy steel knockoffs on AliExpress which I won't likely to look at buying, but at least Fancy Steel made itself popular among kink community, which is a success for them (As most of demographics of people purchasing chastity belt belong to kink community), although I don't really like always associating chastity belt with kink / fetish.
