Let me first say this, since many of my friends asked about it. This is not designed to be on the penis during sexual intercourse. It can be painful and cause tearing of the vagina. Please do not attempt to use it as such. It is designed for CBT play and not to be used on the insides of a woman. /end rant

So, onto the toy!
I found no measurements online or anywhere for the sizing on the rings, so I measured them to the best of my ability. Starting with the largest ring, the last ring is for a leash.

Ring 1: 2"
Ring 2: 1 3/4"
Ring 3: 1 1/2"
Ring 4: 1 1/2"
Ring 5: 1 1/4"
The leather strap is 4" long
The last ring is a D-ring for a leash

This is a cock and ball toy. The largest ring holds both cock and balls, while the other 4 rings just hold the penis. This is easiest put on when the guy is flaccid. Once he's hard, the rings should restrict him a bit. This does not work for average to small men. It is fairly large sized rings and the man will have to be a bit more girthy or the rings will just slip off. The intended purpose of this is for CBT. It can put pressure on the penis when erect and cause the erection to be painful, though my sub finds it very pleasuring. There is an attachment on the end for a leash, which I find especially useful. If you'd like to see how I use it, see the "Experience" section.

This is a relatively small piece of equipment so I would say it is travel friendly. It is leather and metal, the leather piece should be lined up on the top of the penis. The rings are not interchangeable and the toy is NOT adjustable. Just throwing that out there.

This CBT device is not adjustable. The rings are not interchangeable, the buttons are fastened and do not unsnap. They kinda appear to do so, so that's why I'm stating now that they don't. This is made of a leather strip that goes down the top with snapped buttons down onto the metal rings. The snaps are metal too. The sizing for this should probably be considered large, because it won't fit an average guy, it will fall off too easily and won't serve it's intended purpose. The fact that it's leather and metal rather than nylon and rubber or silicone (like some) serves double purposes I believe. One, it's ridiculously easy to clean, two, it doesn't snag pubic hair when you're putting it on or pulling it off. Silicone stretch rings can snag and pull hair out, which isn't fun in the moments of foreplay. It has a leather smell to it because it is made of leather, but it is not a large piece of leather and thus does not smell strongly of it. The only special feature on this that I keep hopping back to is the option for a leash, which I'm raving about. I think a little healthy dose of humiliation by leading a guy around by his dick is good for him.

Now, whether or not you want to say this is easy to put on depends on how big you are. This is a rather largely sized gates of hell device and thus doesn't fit small or average sized men all that well. It will be too big and won't fit around the penis like it's supposed to. In this case, if you tried to use it anyway, it would be extremely easy to get on, but it would also fall off pretty easily.

If you're a girthy guy, while this is still easy to get on, the part that goes over the cock and balls may take a little bit of working or lubricant. I didn't need any, but my sub whined quite a bit over being tugged through it. (To which I can just say shut up because I'm the domme! I don't recommend that though!)

That aside, this performed fantastic for me! It met expectations. And my sub fit okay in it. It worked great for its purpose. It can restrict the erection and cause a combination of pleasure and pain. My sub absolutely adored it and we continue to use it. Our favorite thing is to attach a leash to it. This can be fun to tug at the loop with your finger too though if you want to cause some "punishment" for your man!

This is leather and metal, so all you have to do is wipe this down with warm soapy water. It generally doesn't get dirty for me (though I don't use a lubricant with it). If you do get lubricant on it, you can wipe it down or rinse it off. Just set it out to dry. Leather is pretty resistant so if you wanted to use lubricant to put this on, you could use any, I would think that oil would make the leather feel strange though so I wouldn't use it particularly. I mention down in the packaging how you can store it, but I'll mention it again. This doesn't have to be stored in special way, I keep mine in a bag with the rest of my toys and don't have any problems.

This came in a plastic package, with a picture of a cartoon penis in the five gates of hell. So in any case, it is not discreet. You can use the package for storing, but this doesn't have a problem getting dirty so you can store it anywhere essentially. It doesn't take up much space either. The packaging itself will take up more space that the device, so like I said you may be better off just putting it somewhere with your toys.

I am rating this a 4 because it is for large guys, not average. It is no fault on the way the rings work, just that not all my subs are large, nor are a lot of men that I know or have had experience with. If it came with sizing options I would rate it a 5. But in the end it does perform its intended purpose and I do thoroughly enjoy it.

I absolutely loved this for "puppy play". Once I put the five gates of hell onto my sub, I attached a chain leash to the last loop, and made my sub crawl around on all fours. I dragged him around by the penis calling him my puppy. This brought a level of humiliation (note, humiliation not degradation..) to my sub that he adored. He kept wanting more, being made to walk around on all fours like a dog and being dragged by your penis on a leash provides a level of humiliation that some subs really enjoy. Obviously this can be used for an assortment of other play, whatever is your fantasy.
