When I first got into chastity about a year ago I had a good hunt on the internet for information and settled on a CB6000. Was certainly pleased with it and generally, after a few tries, once the correct combination of rings/spacers etc was found, I found it pretty comfortable. Sadly my keyholder and I parted but have since got in touch with an ex who is currently acting as my k/holder via text and phone call and hopefully a meet up pretty soon. Having a browse on ebay the other day and found quite a nice looking device and put in a quick bid. Ended up getting it for less than £20 - a fifth of the price of the cb6000!! Had it on for the last four days and must say it seems far more comfortable so far than the cb. I'm also very pleased with how it looks. Certainly worth considering if you're looking for a device without spending too much money. I hope the pics display ok.
