NOTICE: I received this product free of charge for the purposes of reviewing it. This fact does not change nor sway my opinions.
When I received the Bon4M Chastity Cages, the overall weight of these cages were impressive. These chastity cages are incredibly sturdy and could easily last a lifetime. Upon further inspection of the cages, I noticed the intricate details that the manufacturer added. All of the rings are engraved with their measurement, which provides the wearer with all of the information they would need when picking out the parts needed for the perfect fit.
Because the Bon4M is made out of stainless steel, the cage does weigh more overall than its plastic/bio resin counterparts. Before wearing the cage for the first time, I assumed that this factor would be a detriment to the overall experience when locked up, but, upon wearing it for an extended period of time, I don’t notice much of a difference between the Bon4M and other similarly priced items.
One of the unique design aspects of the Bon4M that my Domme and I didn’t know about before receiving these cages is the retainer rod is threaded to keep the parts of the cage in place while it is worn. Another feature in the design of the Bon4M is the positioning rods on the cage that sit in notches of the rings to prevent the cage from shifting out of place while locked up. This feature is a double-edged sword because it could potentially pinch the skin of the shaft when putting the Bon4M on, if you are not careful. Thankfully, the threaded rod allows the cage to close slowly, as you screw it into the cage, which minimizes any possible pinching of the positioning rods. After wearing the cage for an extended period of time, one of the two positioning rods did come off of the cage when taking it off. However, it was still able to be placed back on afterward.
The overall design of the cage itself has plenty of slots in it to both allow for proper airflow and it ensures that washing is as easy as possible for extended wearing. An added bonus to this design is that the wearer’s keyholder has plenty of access to tease through the cage and add to the overall experience.
A big concern I had with the cage was with the hinged design of the retainer rings. In the past, I have used hinged-ring chastity cages that were so unbearable to wear because of pinching at the hinge. I was afraid that these cages might suffer the same downfall. After wearing the Bon4M, there was no pinching of any kind from the hinge, the ring, or any part of the cage. One potential downside with the design of this cage is its outer form is one of the bulkiest of the chastity cages that I own. Subsuquently, this may cause the outline of the cage to show more when wearing more form-fitting/revealing clothing.
The one issue that I have with the cage is that the small version of the cage is a bit too large in size for me, but that is not a fault of the design/manufacturing of the Bon4M. In the future, I may consider their newly released Bon4M Micro for a better fit for my size. The inner length of the Bon4M Small is comparable to the CB6000s, such that looking for an all-metal upgrade, the Bon4M Small is the ideal choice.
After extensive testing, I can say that the Bon4M is a top tier chastity cage that, if you choose the correct size for the wearer, it could easily be a lifetime investment for long-term wearing. While I would not consider any high-priced cage for someone who is inexperienced and curious about chastity, this cage definitely falls into my recommendation category for an investment if chastity is right for you.
