Differences/Benefits of CB-3000 & 6000

our CB-3000 has finally worn out after about 3.5 years of use, and we're considering trying the CB-6000.
Can anybody out there tell us the differences, or if it's been improved? Any drawbacks from the previous model?
Help! She's anxious to get her boy back in his cage!

I never had the CB-3000 but I have tried the CB-6000.

I found it to be very comfortable, except for the erections, of course. My skin protruded out of the vent holes pretty much the whole time and I didnt like that. I found it to be very secure although I have heard other people claiming they can get out. There are aftermarket products available to stop that though. They also make the CB-6000 in a shortened version which might be nice for those who are exceptionally small (less than 3 inches soft).

Tell us your story. Why do you enjoy being locked up? Is it 24/7 or just once in a while? Why does your wife like to lock you up? What enjoyment does she get from it? My wife is still unsure about the whole thing. Does your wife make herself available to others while you are locked? If so, how do you handle the emotional feelings that she allows other men the pleasure of fucking her pussy while denying you the same?

I'm 24/7, but I'll tell my story later, I'm more interested in getting info on the device comparimisters and pros and cons. The CB3000 did it's job fine, I couldn't get out of it. It took time, but I got used to night-time erections, and learned to relax through them.
Mine finally gave in after all this time, and split along the seam (Very ego boosting, but quite painful). It's gotten a temporary repair, but it's got to be replaced.
I found the hinge design in need of improvement, as well as the vent locations... all of which looks to have been updated with the 6000.

My wife does wish it still came in the pink color! We're less than crazy about the camo, but the clear is a bit plain.
