I purchased a Bon4 a couple years ago. My only initial complaint was how difficult it was to get on, which I attributed to being aroused by the process. It did get a little easier after some practice, but it still required a fairly drawn out process.
My complaint with the Bon4 is regarding its durability. Granted, I did have it for a couple years, but I rarely ever used it (much to my disappointment). When I did use it, it was only for shorter periods of time (average of 4 hours or so).
After using the device for some time, I noticed the top portion of the cage was starting to tear where the connecting points meet up with the cage. I always hand washed the device with mild soap, dried it, stored it in the provided bag, and always kept it in a cool, dark storage closet. The point being, I treated it with the utmost care possible, and the tears were absolutely not caused by a lack care.
I even contacted the manufacturer of the device to share my concerns. I let him know that I purchased it from Extreme Restraints, he asked me for a sales receipt, but did not say anything beyond that.
I have still not heard back from anyone at Bon4, and I merely approached them as a concerned customer. I love the design of the device, and I would love to buy one of the newer models, but I wanted some kind of reassurance that the same issue wasn't going to happen again.
The total amount of use I have gotten out of my Bon4 to date has been less than 80 hours, and the tears happened somewhere around the 40 hour mark.
Whether there was an issue in the manufacturing process, or the materials used, silicone toys shouldn't degrade over a period of a couple years. For as little as I had actually worn the device, I find it hard to believe that it can be worn long-term without failing even faster than it did for me.

I reviewed this item a long time ago as secure and comfortable. Since then it has fallen off at inconvenient times during the day and a few times at night. To help solve this I stopped using the silicone rings and use just the strap covered in electrical tape, fits tighter but had a ball slip out, then the other and it fell off a few times. I added a rubber cockring I had from another toy, I cant slip a nut through without stretching the ring. The cockring is not so tight as to cut off circulation and I stretch it enough to fit both the boys through. This makes it near impossible for a nut to slip out. I ran the piece of the cage that attaches to the bottom tip of the cage throgh the cockring and locked it on, so far so good.

Fantastic toy, but its easy to slip out when the penis is flaccid. Just a shower, some soap and done. So its more a toy than a real restraint.

I asked my wife to lock me up after some years of interest in the idea, and this is my first chastity device. After some research I decided that something non-rigid would be best to start with and so I chose the BON-4.
My balls are (were) very “high” or “tight” so initially fitting was a bit of a challenge. I started with the second to smallest ring, but it constricted blood-flow to my balls when I even started to get erect. This was very difficult the first night. (tip: try putting your penis and balls though the ring but don't put on the cage and then get good and erect. If you feel your penis crushing your vas then that one might be too tight, or just right depending on how erect you can get with the cage on. Try all the sizes till one barely fits, in short)
I switched to the largest ring, but I could easily slip out of that. Finally, I settled on the second largest ring. I've been wearing it for a few days since; in public, at work, and even at the in-law's overnight!
For the first day wearing my current ring I was very nervous; not so much about showing, but about safety. My usually tight sack wasn't used to my balls hanging so far out, and a few times I was tempted to ask to be unlocked. It was very uncomfortable, but I found out it was just my skin stretching out. Luckily we were out and about and I resisted the urge, checking on myself every hour.
My fears were unfounded; everything was okay and the mild pains subsided. My skin was stretched, but at worst it was a bit red. Eventually it started to feel “right”. The key was to keep pushing the cock ring against my body as I adjusted. Some lotion to keep the skin lubricated to allow for natural motion. I slept through the night, save for a normal trip to the head.
Tonight I was allowed to unlock to clean and dry myself out. After making sure everything was A-OK I eagerly locked myself back up! Once the initial discomfort of my balls being stretched out passed it all started to feel very comforting. I described it to my wife like a “chastity hug” always there reminding me why I asked to be locked up. Sure, trying to be erect is a little uncomfortable, but it doesn't cause me any PAIN and re-enforces the idea again and again. Every time my body tries to get a little erect (which is more common than I thought) I feel it and get a little feedback. A nice low-grade arousal.
In short: I have a grower cock (2” → 6”), high tight balls and am new to chastity. This device is right for me after working (CAREFULLY!) through the initial discomfort and recognizing what ring fit me best. I'm quite happy and, strictly from a comfort standpoint, would rather feel the comforting warm grip of my chastity cage than nothing at all! I'd recommend trying this device out to anyone interested in chastity.
