Hello All, I'm the manufacturer/designer of a plastic lock for the cbxxxx series of chastity devices, although i am in no way affiliated with the makers of the cbxxxx range. The lock is airport safe, does not rattle, is reusable, uniquely keyed, tamper proof and has a very low profile(installed it's a 7/16 cylinder that's about 1/2 inch tall.), so it's more discreet than a padlock. It fits both the round pins of the cb3000/2000 and the oblong pins of the cb6000. I think it's a better solution than a padlock or single use plastic lock, but i could use the opinions of others and would like to get the word out. To that end i would like to offer a free lock to a handful of people, all i ask is that they post an unbiased review of it on these forums(or any others, for that matter). Just send me a p.m. that you're interested. I'll reply to the top 3 or 4 and provide my address. Then all you need to do is send me a S.A.S.E. (A regular envelope, addressed to you with a first class stamp), which i'll use to send you the lock. At this time these are distributed through lockeduplove.net and you can view pictures of the lock there. Sorry folks, but i cannot make heads or tails of the mail system for this forum. I've already lost the first couple mails i've viewed. seems like after i open them, if i don't reply immediatley, they're gone. contact me direct at email@example.com And to the ones that have already disappeared, if i recognise the name, i'll bump you to the top.
