The CB range are only any good for short term, long term there's no way round spending a lot of money on a customsteel belt....
I'm currently working my way through a 1 year sentence in a chastitysteel CS500, been in since November 06......
Not bulky through clothing, doesn't interfear with working or any activity, very comfortable, no problems at all really, so much better that the "off the shelf stuff"
If we'd gone steel in the first place it'd of saved more money that we wasted of CB's and the like and paid for itself twice over
