Chastity device discussions and reviews discussion

Hi there, I am about to embark on a foray into the custom built device market. I have messed around with the other toys out there cb 6000s and holy trainer. I am looking for something more secure with a better fit and ease of cleaning. My mistress tells me she wants to lock me up long term. The above devices seem to be the way to go but am looking for a direct comparison of the two. Is there any one out there that owns both? Which do you prefer and for what reasons. I am pretty small and have been able to escape from both the cb6000s and the holy trainer i am looking for a more secure device in my reading and research these two again seem better but does any one have experience with the anti pull out options fitted to the contender and jailbird. Thanks Dirty Dianna
