Having worn one, finally, I’m ready to offer a CB-6000 review on the first popular mass-manufactured chastity device ever made. The CB line of penis cages likely has persuaded many guys to give male chastity a try for the first time. Based on all the positive reviews I’ve read since I became interested in chastity, it is one of the devices I recommended in The Hitchhiker’s Guide to Male Chastity to chastity beginners.
Introduction
CB-X manufacturers two CB-6000 models, penis cages made of medical grade polycarbonate, a highly durable plastic material. The standard model, the CB-6000, has a 3-1/4 inch cage with a 1-3/8 inch inside diameter. I tried out the other model, the CB-6000S (The “S” denotes short). It has a 2-1/2 inch cage and the same internal diameter. As a grower, not a shower, I prefer shorter cages.
Meet The CB-6000
The CB-6000S is another ball-trapping device, but it comes with more than the usual three parts.
- 5 base ring sizes—1-1/2″ ID, 1-5/8″ ID, 1-3/4″ ID, 1-7/8″ ID, 2″ ID.
- 3 different locking pins
- 3 different spacers
- Brass padlock
- 5 numbered plastic tamper-evident locks
The various base ring sizes, locking pins, and spacers are intended to give wearers options aimed at achieving something close to a customized fit. The different pins and spacers allow flexibility as far as the cage-to-ring gap, which I think is a useful feature. The only measurement needed to order a CB device is the flaccid penis length.
The CB-6000S base rings are a little different from those of other devices. They are round rings with a gap at the top. Two other crescent-shaped pieces are supplied that close the ring into a complete circle. One has two white plastic pegs that help support and stabilize the unit while worn. It is inserted from the back. The second piece goes on the front of the base ring and slides over the two white posts. The locking pin is also inserted from the back. It isn’t perfectly circular by design so that it won’t turn after insertion.
I suppose the three-piece design of the ring makes it easier to put on by someone unfamiliar with putting on a ring worn around the penis and behind the testicles. But I found it easier to assemble the entire ring first and then putting on as I do any other base ring. Instead of rounded edges inside, the plastic base rings have squared-edges.
Fit
With the flexibility of the selection of base rings, locking pins, and spacers, I was able to obtain a good overall fit with the CB-6000S. At 2-1/2 inches long, and with the 1-3/8 inch ID, the dimensions of the cage are the same as my custom-made Mature Metal device, giving me the perfectly fitted cage as expected. However, because of all the combinations available, it did take some experimentation to get the final fit that felt best.
Knowing that finding the best fit would be a trial and error exercise, I approached it systematically. I used the largest ring and the longest locking pin and spacer combination first. It felt reasonably secure even though the 2-inch ring was larger than what I usually wear with my steel devices. Because the plastic cage is so lightweight, I went for comfort using the larger ring because of the hard-edges inside it. I wore the device all day without any problems.
After going to bed, while rolling from one side to the other, my left testicle popped out of the base ring. Since I had to get up and remove the device to put it back on correctly, I changed to a 1-7/8 inch ring, and the middle-sized locking pin and spacer. That got me through the first night wearing the cage without further incident.
On the second day, I replaced the 1-7/8 inch ring with the 1-3/4 inch, my usual size, and tried the shortest locking pin and spacer. The ring was fine, but I found that combination less comfortable and went back to using the middle-sized pin and spacer. That turned out to be the best overall fit, and I kept it for the duration of my wear test. On the whole, I found the fit better than a lot of the off-the-shelf steel cages I’ve tried.
Comfort
Mostly because of the way the base ring is designed with the square edges inside, I didn’t find the CB-6000S to be as comfortable as my well-fitting stainless steel cages. I wouldn’t say I experienced any actual discomfort, and I didn’t suffer any abrasions or tender spots from the ring. It was more like uncomfortable in a sense I can’t imagine I’d ever not notice I was wearing the device. There was a spot in the middle of my scrotum where the ring made its presence continually felt. I think in time, I may have grown accustomed to it, but three days of wear was not long enough for that to happen.
One thing I did like was the device was so much lighter than steel cages. That was one favorable trade-off.
Except for the first night when my testicle escaped, and I had to get out of bed and fix the problem, I didn’t experience any difficulties sleeping while wearing the CB-6000S. Since the cage was the proper size for me, there were no issues with the spontaneous nocturnal erections discomfort.
Hygiene
Hygiene, I think, is the biggest shortcoming of the CB-6000S. It’s a solid cage that encloses the penis. While there are side vents that are supposed to be there for hygienic reasons, I don’t think they serve any real purpose in that regard. Keeping the contents of the cage clean while wearing it without special supplies would be problematic at best during long-term wear. The only realistic option would be removing the cage periodically for a thorough cleaning.
Urination was another issue. I tried peeing while standing once just as an experiment—a bad idea. Expect to sit while peeing while wearing this device. That’s not unexpected with most any chastity device, but the CB-6000S was worse in the urination department than any other device I’ve worn.
Recommendation
The CB-6000S accomplishes what it is designed to do, though it isn’t the most comfortable device I’ve worn. That’s almost entirely because of the design of the base ring. If CB-X would only round the inside edges, I think it would be a huge comfort improvement. Also, from a purely aesthetic perspective, I wasn’t impressed. The CB-6000S is an ugly unit. Still, because of the price point and the customization options it offers, I stand by my past recommendations that it is an appropriate and serviceable device for those just getting started with chastity. Many knowledgeable people I know insist that The Holy Trainer is a better option for beginners than the CB-6000 devices. But since I haven’t yet tested The Holy Trainer, I can’t make that claim.
If you’re thinking of buying a CB-6000 device, avoid buying those offered on Amazon and eBay. The CB-X website states clearly neither is an authorized CB-X retailer. You won’t find the genuine CB-6000 on those sites. So, if you purchase a “CB-6000” from either place to save a few bucks, you will get a knockoff version.
