Ordered this on Saturday night and it arrived Wednesday morning, securely and discreetly packed.
After a quick shower opened the package up and without second thought fitted the cage straight away. The choice of rings and pins made fitting easy; with a small amount of fiddling (and waiting for subsidence) the lock was closed down in under 5 minutes.
As a first timer in chastity, wasn't sure how I would react or how long I could handle it; however I fitted the cage at around 8:30 last night and it is now 7:30 the next morning and it is still on, still comfortable and still a prison !!
Once on, the cage is immovable; there is no room for escape at all. I was not bestowed with the largest member, hence the 600S; and I worried I could "fall out" but there is no chance of that, and the feeling when that lock clicks down cannot be described!!
Only tip I would give so far is if you plan to wear this long term, invest in some snug fitting pants; with boxers on there is a slight tell tale bulge and the lock tends to clunk against the cage; with tighter pants these problems go away.
Hoping to get to 24 hours in first session and continue training with the cage until I can hand the keys over; watch this space!!
