My husband solipsist and I have been exploring orgasm control and chastity play for some time now. Sol has been wearing the CB6000 (which you can also buy at S(A)X) since it was very kindly gifted to us by friends last year. We’ve had enormous enjoyment out of this device. However because it’s plastic main cage has split five times under pressure … a problem encountered by many wearers of the device … we’ve reached the point where we only take the CB6000 out for specific play now and then. Which means we’ve been searching for a more long term chastity device.
We’ve had enough experience with chastity devices to understand that there is no one perfect chastity device out there that we can recommend to those of you who ask our advice in their search for “the perfect devise”. Everyone’s anatomy is different. And therefore everyone’s experiences of each device are going to be different. What’s comfortable for you may not be comfortable for us, and vice versa. So please keep this in mind when you read the following review.
We’d been very interested in the Birdlocked, the first silicone device on the market. However the price was horrifically high at the time, and good friends who’d purchased the device had had problems. It was at this point that we visited S(A)X’s leather workshop at Byron Bay, and discussed reviewing the just released BON4 - the second silicone device on the market.
You can read the full review on my blog here. It’s long and very detailed, but someone on Fetlife did call it “awesome”, which was nice. What’s important to cross post here I think, are the device’s technical details and then our conclusions.
THE BON4 - TECHNICAL DETAILS
Pretty, isn’t it?
You’ll find the BON4 website here. The BON4’s technical details are reproduced on S(A)X’s page about the product: “The Bon4 Male Chastity Device … is supplied with three ring sizes of flexible silicone that interlock with the comfortable silicone cage. The device is fully adjustable and will fit anyone. Simply choose the cock ring that fits the best and fit it around your penis and testicles. Then attach the cage and interlock them with the silicone belt. Add the padlock and lock things down!”
“Approx. 4.3 (111 mm) inches in total length; internal cage length approx. 2.5 (65 mm) inches in length; cage opening approx. 1.4 (35 mm) inches. Ring sizes are approx. 1.6 inches (41 mm), 1.9 inches (47 mm), and 2.1 inches (52 mm). The fully assembled weight is 90gms”
The manufacturer also makes the claim: “Because BON4 comes with 3 different sizes of cockrings. it will fit anybody”. This claim worried me right from the start … and I was right about that…
MISTRESS160 AND SOLIPSIST’S CONCLUSIONS

We wanted to complete a two week period of wear before reviewing the BON4 for S(A)X. This review period was extended due to sol’s injuries and so I could document the underhand tactics of Birdlocked, who flooded the internet with fake BON4 distribution websites selling fake copies of the BON4 in mid June 2010, two months after the BON4’s release.
For this reason I sincerely recommend anyone wanting to buy the BON4 purchases it from a reputable distributor like S(A)X.
During our first week wearing the BON4 we found lots of positives. As a wearer, sol found it more comfortable than the CBs because of the soft silicone. It allowed him to sleep through the night. It fitted better under clothes. It was great for travel (both flying and driving). And there was no constant worry about the device splitting (like the CB6000). He did experience some problems peeing in the device, which we thought might be made worse by his PA piercing.
As an owner / keyholder I really liked the look of the device and the fact it’s soft to touch and yet cuts sensation. Most importantly, from a psychological point of view the device worked extremely well. While wearing it sol quickly achieved the submissive mindset I enjoy … which became even more pronounced when the device was removed for play. So the BON4 certainly works well as a chastity device.
However after a single week, sol had enough small - but I have to be honest here, extremely painful - injuries that they added up to significant discomfort and required the device’s removal for several days and finally, the termination of the two week trial. You’ll find photos in our original review.
We identified two reasons for these injuries.
- The first was poor fit. Sol falls between the ring sizes currently available with the device. For him one ring is too tight, the next sized ring too loose. Ironically while BON4 only produces three cock rings, Birdlocked has produced it’s fake BON with five differently sized rings … one of which would have fitted sol perfectly.
- The second reason was poor design, with severe pinching occurring where the device joins together. For more details see my full review.
Our trial has proved that the manufacturer’s claim that “because BON4 comes with 3 different sizes of cock rings it will fit anybody” is incorrect. If we had the option to discuss the design of this device with the BON4’s manufacturer, we’d suggest:
- having more ring sizes available, to widen fitting options. They can still sell the BON4 kit with three rings but at least advise purchasers that other sized rings are available if required
- altering the design of the BON4 cock rings so their edges are further rounded, to avoid rubbing / pressure injuries (Birdlocked got this detail right)
- slightly enlarging the center hole to help with the peeing problem, so that pee does not build up in the cage (which Birdlock avoids with the extra air holes
With regret we cannot suggest a solution for the severe pinching where the device joins together.
So, do we recommend this product?
As a short term chastity device, absolutely we recommend it. For all the positive reasons we’ve given above. I think it is especially good for men who have active lives and for men who travel. For example, it would be an ideal device to lock your partner in prior to a short business trip.
For longer wear, we simply can’t recommend it because we experienced too many injuries. It’s very important you make sure you fit the rings that are available before you purchase it - if you’ve worn a CB device you’ll have worn similarly sized rings. My original review discusses how to determine your ring size if you have not worn a different type of device that uses them. I do not recommend you buy the fake BON rings from Birdlocked, even if they have a size that fits you. Apart from the ethics of such a transaction I have no idea whether the rings are well made - they may have even sharper edges than the BON4’s.
I sincerely hope that very soon the makers of the BON4 will offer more rings. At which point sol and I will be able to purchase one that fits better and the BON4 will move from a short term chastity device to one that we can use for much longer periods. Although we’ll still need to keep an eye on that pinching where the two parts join.
I think the BON4 - and silicone as a base material - has potential. Silicone offers amazing opportunities as an alternative to metal and plastic devices. Yes, there are teething problems … but what new chastity device doesn’t experience them? And as all of us who are interested in male chastity know, what works for one person - or in this case, one reviewer - doesn’t for another. Everyone’s anatomy is different, and therefore their experiences of each device is different.
Sol says that the next generation of BON (meaning the BON4 manufacturer’s future version of the device, not the appalling ripoff by Birdlocked) will probably be the perfect male chastity device. And I agree. But believe me, you can still have a hell of a lot of short term chastity fun with the BON4.
