Chastity device discussions and reviews discussion

Hi everyone, I’m hoping for some advice. My experience with chastity has been limited to sessions with my partner using the Oxballs Cock-Lock. It’s excellent for playtime but relies on his presence since it doesn’t feature a proper lock.

I’ve always desired a ball trap that is either impossible to escape from or difficult to re-enter if you do manage to get out. My soft length is roughly 7-8 cm, extending to 17 cm when erect.

Preference goes for plastic/silicon construction and no requirement for PA. The Vice device seems very promising based on appearances, yet there are barely any details from actual users.

Therefore, which devices do you own where the penis cannot be pulled out, or becomes hard to put back in once removed? Also, if anyone has used The Vice, what was your experience like?
