This item works just like it supposed to – no more slipping around satifying himself! He is locked up and only I can determine when he has been good enough for a release. Easy to use and performs as intended. Removal is necessary for proper cleaning. Adjustment period is about a month if you slowly ease him into the CB-6000s. Very discrete but any man larger than average will need the CB-6000 as the tube fills up quickly and the extra 3/4 inch could be needed.
