i had one of the originals. While i loved the concept, the product had far too many flaws. A big problem for me was that the gap between the cage and the balls was way, way too small - it looks like they addressed this in the new version (which is a positive).

Another big problem was the application software and it's lack of features - i felt like there were some "in between" modes that were missing. For example, a mode that gives up control to a Domme, but still allows the wearer an "out" - it would still keep basic control with the Domme, She'd just be notified of the infraction. i felt like such a mode would likely be the most popular, because then you don't have to worry about things like emergencies or the Domme losing their phone. Plus it could enhance the play (i.e. setup punishments for infractions).

And that's not to mention the security flaws that popped up....
