CB3000 Assessment, Ideas and Additions

Submitted by: Susan and Martin

Introduction:

As some of you know I make male Chastity Belts, mostly the thong format Florentines (sometimes called Venetians). My tester and I have been interested in the Miller devices for some time and decided to buy one and test it; we also bought a KSD ring to test that. I wanted to learn from this design, possibly make some DIY additions for it; and possibly learn from it.

1. Initial views & findings:

We were quite impressed with the quality and finish of the device. It may seem expensive for a plastic product; but in context and in this category we feel it is really quite good. Its main limitations are low security and a lack of design planning for men with intact foreskins.

2. Fitting and setting the components sizes:

We found that it was best to choose a cuff (or "A" ring) one size larger than a tight fit, but use a relatively short locking pin, leaving roughly 10mm between the "A" ring and cage. Tighter cuffs cause the balls to go a bit blue and don't really make the device more secure.

3. Experiences with daytime and night usage:

Like most users, my tester found that a 4am wake up call (with a moderate erection) was a problem. It seemed to be he bodies way of telling him to go and pee. It also pushes the device away from the body and squeezes the ball sack, which was painful, and makes urination difficult. This did diminish over time but never went away; Florentine CBs don't suffer this problem to the same degree.

4. Issues for men with intact foreskins:

We both feel that the makers are have not considered men with intact foreskins properly. The aperture at the front is quite large, so the foreskin gets forced through this hole and pinched between CB3000 cage and clothing. We found that it was best to pull the penis back a bit so that the foreskin sits further back in the tube mouth. A smaller aperture or a series of small holes might work better.

5. Security and concealment:

I was surprised to find that the CB3000 is more noticeable, under clothing, than a good thong form CB. The CB3000 is more comfortable but it does stick out; and some form of waistband support seems to help. Direct security comparisons are difficult; but overall a real Chastity Belt is more of a discouragement to unauthorised activity. With the right additions, the security of both devices can be improved; but they both need extras to get there.

6. The KSD-G2 and it's sizing:

This is about the best of the "off the shelf" pull out prevention devices. We both have concerns about its safety. I ended up seriously reshaping both our KSDs; tapering the aperture and carving away a lot of material at the base of one of them. We don't use it regularly; and would never use it for an extended period. It does create a backpressure against urine flow and this alone makes it "less than completely safe".

7. Making and testing DIY add-ons:

I made, and we tested: single, two, three and four point support systems for the CB3000. These do help with some of its problems, but also add complexity and some new problems. On balance, some form of simple support is probably worth trying.

More complex support systems (some of which almost turn the device into a full chastity belt) never made this device as good as a Florentine, or thong format metal CB.

The single biggest improvement to date was frontal cage bars. Using 1.5mm SS rods I made transverse bars across the frontal opening, at 6mm intervals. These worked really well for my "intact" tester; we have yet to find a downside; but fitting them was a VERY delicate and risky process.

I made and tested several "aperture restrictors" made of bits of unused rings etc. These are safer than the KSD-G2 but also less secure. Only the individual can decide if these devices are really worth it?

Conclusions:

Oh boy, the CB3000 really is an interesting device; it's changed the face of male chastity over the last three years. The tube is a tour de force of design; I can imagine a better tube, but I don't know of one. The rings are very well made; but (in my humble opinion) they are the WORST part of the design! The cage should have been slightly curved; to avoid rubbing against the balls as much as it does; and a simple adjustable support band (even as a option) would have been very welcome. The rings could have been as thick or thicker at the top (to allow for the tube mountings) but should have been slimmed down to a 6mm round section at the base. Granted this would have meant a change of material; but user experience would have been substantially better. I also think the rings could have been silicone dipped; which would have reduced the possibility of skin irritation. All in all a most instructive device; much of it is brilliant, but some of it is a real step backwards in CB design. I hope A&L come up with something even better next time; but they need user feedback to do that; so write to them and tell them how to improve things.

Cage Bars (Fiddly but worth it)

This is a quite difficult alteration, and it does damage the cage; so it is permanent.

Simple Two Point Support (Temporary)

This is simple to make, works well, locks on and is non-metallic. A&L please try making it.

Three Point Metal Waistband Support (Permanent)

This device worked but was not that comfortable; but it was VERY secure!

4 Point support attachment (Permanent)

I would love to show you how the rest of this system works, but the shots include a person, so I can't. It was successful, but it then evolved into something better still (no "legal" pictures yet).

Five Point Harness (Permanent)

This was the most secure yet flexible solution we made and tested. It locates on the guide pins and locking pin with two nylon buttock straps (as above). The waistband is a plastic coated metal cable with alloy connecting pieces and end caps. It looks great and provides a very flexible but firm support. If I could make it customer adjustable I think a lot of CB3000 users would want one. Unfortunately I can't show you because the pictures include a person. Isn't the American legal system a real peach?

Kind regards

Welcome back Altairboy, we missed you!
