Greatcornbow FancySteel are really for show and not a patch on Mysteel, Neosteel or Tollyboy. They're certainly not fit for 24/7/365 or longterm.
Nothing is fit for 24/7/365.
Fancy Steel have designs that made chastity belts accessible to a wider range of people, and far more suitable for everyday life. I can move, bend, stretch, sit, stand, drive etc, and I don't have to buy a new wardrobe in an effort to hide my hardware.
They are comfortable and secure... even with a slimline cable belt, once that shield is locked in the right position there's no access to your private parts without a key or industrial tools.
Personally I really like that someone was thinking outside the box, and that they made the first really unique chastity belt design in hundreds of years.
