Great for long term chastity
Great from order to delivery. Product is amazing, highly recommend for 24/7, 365 days wear....the best!
The product itself is great, as long as you never need to order replacement parts
lose a piece and need to order a replacement and don't live in the Netherlands. I recently lost a spacer, so went to replace it, after a pretty thorough web search, I came to the conclusion that finding replacement parts for these pretty much only come from Bon4 directly. A new set of spacers is $24, which is fine, but the shipping charge is $24 as well. I know for a fact that FedEx isn't charging them that much money to ship a few tiny little metal rods to the US.

High quality product and unparalleled customer service from an owner operator who cares about customer satisfaction. I made a mistake on my order (my fault) and they helped rectify for me.

Outstanding experience from start to…
Outstanding experience from start to finish! The website was very detail oriented and made my key holder and I feel confident about buying the cage I did. We really liked the video and 360 degree imagery of the cage. The total attention to detail in every aspect of the cage is awesome!
The Micro cage arrived quickly and in perfect condition. That saying "You get what you paid for" holds so true in this product. It may cost a bit more for than other cages but it was so worth it.
To the entire Bon4 team/Management keep up the outstanding work your doing. You all are truly masters of your craft.
Respectfully,
Total satisfied caged customer

Peter was great at responding quickly and solving my issue even quicker. The customer service is top notch and my replacement cage fits perfectly.
Great product
Great product, it's very well made and has a nice heavy feel to it. I ordered the small and micro versions. Finally I went with the micro since I am quite small flacid. That’s great about the double package. With the variaton of rings and spacers its very likely to find your perfect fit.
The only complaint i have is the screwing mechanism since, for me it was quite tricky to make it fit. So i sanded down the threaded pin so only the lock holds the cage in place. Now its perfect.
Anfast but I won’t anymore.
I can’t believe how well it is made. It fits like. A glove and the shipping was insanely fast.
top experience
Quick delivery, exactly as ordered.
The information on the website about sizing and measurement were helpful and accurate.
It arrived just fine
It arrived just fine. Good thing I have tools. There was just one big problem. The guide pins would only line up with the smaller rings and would not fit the larger rings. I had to chamfer out the holes and work with for along time before I finally got it to work Good thing I have tolls so was able to make it work. But to be honest I should not have had to do that at all.
Best chastity cage ever
Best chastity cage ever. Its locking system is simple and strong. Comes with many sizes, so easy to adjust and find the right one for you. What really sold me, though, is that the ring is designed as a loop which folds on itself: way easier to put on. The other designs (a classic cockling style) is not comfortable for me to put on (big balls, here). If I had one design suggestion for the next generation, is to have a variant where the space between the ring and the shaft cage is slightly wider, to allow for a bit more freedom for the ball sack. Overall, best cage ever!

When notified they had sent a wrong size.
They immediately shipped the right size on them!
Great Product
Quick order confirmation, speedy FedEx international delivery and most important, a perfectly engineered and manufactured product. Should have shopped here the first time rather than wasting money on cheap products that don’t fit or break after use.
High quality product
High quality product. Just what we were looking for. Keeps assets secured comfortably.
Love it
Love it, no pinches other then when the lock moves around. Took a few trys to find the size ring to work well, so glad it came with so many options.
Great device
Perfect device, won't be coming off anytime soon except to size down to the micro in a few months!
