Comfort in steel
Review by John posted on 23 April 2014
SWMBO did buy me the Masters Extreme Steel cage, which has one major shortcoming - the screws are VERY easy to lose. So she bought me this (with the small cage) which, to my great surprise I have found more comfortable than the CB6000s and much more secure. It hides well in clothing and has a well shaped hole for urinating. Looks like a long residence in this new home!

Excellent well made device
Review by Geoff posted on 27 November 2015
This is the fourth chastity device I have purchased and having spent considerable time pondering different options the arrival was eagerly anticipated. Well it certainly hasn’t disappointed. It is slightly fiddly to fit and two pairs of hand though not necessary do certainly help! An initial concern was that the weight of the device caused it to pull down. Switching to another of the supplied rings with a slightly smaller diameter cured this without causing discomfort.

My wife and keyholder reacted with a wow when she saw me in it, “stunning” was her verdict and having verified I was securely confined gave it a full thumbs up. As a couple active in the cuckold lifestyle it is important to both of us that I have a device that not only keeps me securely restrained but also looks good when we are “entertaining”. The Bon4m is a big success on both counts and a big improvement on our old devices.

I have the small version, it’s an almost perfect fit, very comfortable and feels fabulous to wear. After a few hours day time wear without issue the first big test was an evening visit from our bull which it passed with flying colours. He commented that it was the best looking cage he had seen and we all felt my new Bon4m had enhanced the evening.

If you are looking for a well made and stylish chastity device and are not ready or willing to pay the serious sums necessary to go the custom route then this well engineered cage is well worth your consideration.

Bon 4 Metal Review after 10 days of constant wear
Review by Locked for the last 18 months posted on 18 August 2014
The Bon4M is my 4th chastity device and is very good. I went for the small size to make sure it was comfortable and not to visible under clothing. The cage is well finished on the outside and looks great. The inside is not polished but is smooth enough and they provide a small piece of abrasive paper just in case. It is quite heavy though and I found it more comfortable using a ring a size smaller than normal so that it stayed in place. The only disappointment with the Bon4M is the hinged rings. A solid one would make it 100% and a real 5 star product. Still I've been locked in it for over a week and it feels good so another great product from Uberkinky.

Bon4M Small
Review by Dan posted on 19 March 2015
Over the last few years I have worn a variety of ball trap cages and this is by far the best.

I started out wearing the CB6000 as it is the most commonly available and even though I enjoyed my first foray in to chastity, it wasn't too long until it split along the seams.

I replaced that with a spiral cage made of metal and that was great as the weight added a little something extra, but it felt quite cheap and generic in design.

That's when I decided to try the Bon4M and also to try out the small size, as even though the other cages felt like they were the right size, allowing room to grow is not as effective as total restriction. The Bon4M small keeps me tucked away nice and tight.

It is well made/machined and they even supply you with a little bit of sand paper to remove any sharp edges (but this wasn't required for mine.)

It is vented so it stays clean and feels clean.

It has a nice weight to it, you always know it is there but very comfortable.

The hinged ring doesn't pinch me and the multiple sizes that were sent allowed me to find just the right fit.

I can't think of any negatives! Maybe if they redesigned the locking pin so that you could somehow encase a padlock instead of having it dangling. This would mean that I wouldn't have to use a rubber band to hold it tight, and it would also add another level of security as you could hacksaw the lock off!

Great product, very happy!

Excellence in steel
Review by Chase T posted on 30 September 2015
I have worn this 24/7 for 3 weeks. My wife has let me out every 3rd day to throughly clean myself, but to be honest the vents allow adequate water and soap flow for that. It is nicely weighty, and I know some people have had issues with rough edges requiring sanding down - I have not had any problems. Two minor gripes 1) the good sleeve on the ring stops your skin getting caught in the hinge but can get quite tacky and uncomfortable unless lubricared. 2) the lock could be a bit better - it works, mine is pink which She likes but I doubt if it would take much to break it. Other than those minor issues - if you're into chastity - buy it! I had the cb6000, cb6000s and the stainless steel spiral cage - both CB types split and broke and the spiral one allows the cock to swell up between rings making for very painful pinching. Hope this helps you.

Locked up nice and snug in this shiny new device
Review by kinkysubboy posted on 26 November 2015
This is my third chastity device but the first in metal. I've previously had a CB6000 (broken now) and a Birdlocked Mini. We enjoy chastity play and wanted something a bit more aesthetically pleasing than silicon - this delivers on that front!

The four rings allow you to adjust for size. It may take experimentation to find which one's tight enough for you to not be able to pull out, but not so tight that your balls don't go blue (same as any other device, really).

The split ring means it's easy to get on - watch you don't pinch your skin as you close the ring though! It's pretty comfortable to wear until you start getting hard, and that's where the edge of the ring can start to bite - it's not smoothed off enough for my taste - I'd prefer it more rounded. Some users have put silicon sheathing all the way around the ring, which I might try.

I chose the Bon4M in small. I'm 6" ish hard, 3.5" ish soft. I pretty much fill the Bon4M small when I'm soft, and there's very little room for expansion. This device locks me in nice and tight, and makes full erections pretty impossible, and rather painful. Which I guess is somewhat the point. I wonder whether I might get more sleep with the longer shaft, as it would allow for more expansion before my erection starts pulling my balls forward with it, which is where the ring can start biting and wake you up.

Finish on the inside could be a little smoother - at some point I might get a tool and smooth off a few bits. It's not as smooth as the outside. Saying that, I've worn it for three days on the trot with no problems apart

My other half loves the look of the device. She's wanted something for me in metal for a long time now. This satisfies her. It's shiny, neat and very solid looking. I really like it too. It's pretty comfortable to wear but you're more aware of it than a plastic or silicon device because of the weight. Feels more serious.

It's our favorite chastity device so far.

Brilliant cage
Review by Matt posted on 14 July 2016
This cage is everything I hoped for. Well made, good fit and totally secure. Well worth paying this price for the real thing. Comfortable to wear long term - plus if you want an extra horny twist you can add the spare cock rings behind the cage and lock them with the extra pin. Very hot..

Bon4M Small
Review by RevaC posted on 31 August 2015
This my first chastity device, and even as a newbie to the world of chastity, I am so pleased with it. I gave very careful consideration to buying this model, as I regard it as something which may be in use for prolonged periods of time.
The Bon4M Small is a perfect fit for me, and I was fortunate to receive the redesigned model which seems to be well machined with no irregular or sharp edges. It's easy to put on whilst flaccid, once the appropriate sized back ring has been selected, and its weight is not excessive, particularly considering that it's carried within one's underwear as support for it for a lot of the time.
Having tried a Perspex device, I much preferred a metal type one as it's comfortable and also very importantly is hygienic to wear and maintain.
Dealing with Uberkinky is also to be highly commended, first class service, help and advice from both Diane and Fiona....one couldn't wish for better. Thank you so much!

Bon4m s
Review by Jo posted on 10 October 2015
Bought to replace a CB6000 which being plastic has longer term wearing issues and splitting. The build quality is not quite as good as expected with a number of surface (cosmetic) marks and dents on the metal surface. However, the rings are sturdy and well engineered and the 4 sizes give a good range of adjustment. It is really comfortable to wear and although metal and quite heavy it does not slip as other metal devices I have owned. The vents and holes are in the right place making 'stand up wee's' possible without the fear of deflection! Overall I am really pleased with this product and it looks good as well as not being too bulky to be detectable under jeans. It is not possible to adjust the gap width but for most people this should not be an issue.

I have one of these devices, which I bought from you. No problem, except that my lady says that it is too obtrusive when worn in public under normal clothing. Is it possible just to buy a BON4 short cage only as an alternative for wearing under normal clothing in public?

Answer by: Mistress Victoria (Admin) on 4 Nov 2014 13:37:00
Hello,

Unfortunately the manufacturer does not sell the cages on their own. If this ever does change we will definitely stock the cages in both sizes.

Thanks for such a quick reply. Reason for checking was that the of silicon Bon4 models the longer one is lasted as having a greater diameter than the shorter one. So, just to clarify, the steel ones are both of the same width, is that correct?

Answer by: Mistress Victoria (Admin) on 7 Dec 2015 13:57:00
Yes they are the same measurement.

i've had two metal chastity device before both made my cock swell up and become infected would this do the same

Answer by: Mistress Victoria (Admin) on 10 Oct 2014 09:22:00
Hello,

It would depend on what caused the infection. Did you have a cut on your penis before you put on the device or did the device have a sharp edge that cut your skin?

Was it a rash with raised bumps? if it was then you may have had an allergic reaction to the nickel content in the metal. If it was an itchy rash due to a metal allergy, then the Bon4 will be fine since it's made from hypo-allergenic silicone material.

I currently have a Bon4L but have had difficulty wearing it as the silicone folds and causes the skin to be pinched. How does the Bon4M compare size wise to the Bon4L?

Answer by: Mistress Victoria (Admin) on 22 Nov 2016 16:02:00
Hello,

All the measurements for all of our products can be found in the additional information section of the product pages. Overall the Bon4L and the Bon4M are close to the same in size as far as cage length, cage inner diameter and cock ring sizes. Hope this helps!

Hello,

At this time the genuine Bon4M devices only come with hinged rings.

Question by: Steve on 4 Dec 2015 10:42:00
Show answers...
I see in the given specifications that the internal diameter of this device is 3.5cm. Is this true of both lengths? I ask this as the shorter silicon model is listed as having a diameter of just 3.2cm.
If indeed this is an error, could you perhaps direct me to a model of at least 3.5cm diameter but with no more than perhaps a 7cm insertable length? I do appreciate the option of having one custom-made but at this early stage my budget is no more than £100-£150.
I'd really appreciate your help here.
Many thanks.

Answer by: Mistress Victoria (Admin) on 4 Dec 2015 11:01:00
Hello,

I've taken one of each down to confirm the measurements. The opening of the cage portion is oval in shape and is 3.7cm horizontally and 3.5cm vertically each with minor variations due to the manufacturing process. Hope this helps.
