Early ownership review - Excellent. Review by XD45c

I've had this for about a week and a half. I've probably worn it 8 - 10 hours. I'm between a 10 mm and an 11 mm right now. This is a very snug fit and is an awesome piece of kit.

Finish - perfectly smooth.
Weight - hefty. if you relax (soft) when wearing it, it will start to slide out.
General shape, may not be for everyone but I really like it. The last "bump" to go in feels really large the first few times you use it, but they may just be me. The curve to the glans ring is large enough not to rub the bottom of the little general. :)

Overall - excellent purchase.

What I want, one "just like it" but smooth, around 7 inches long, starts at 8 or 9 mm and goes up to about 10.5 mm in the first half to 3/4 inch would be about perfect for me.

One of a kind penis spine Review by newby

I ordered this item about a month ago. I kept working the end in my penis, finally getting it in. What a feeling! Today I finally inserted it all the way. Fits is fantastic! I plan on wearing the spine for a while! Keep up the good work CHAIN GANG! You are awesome!

Oh what a feeling! Review by Santa

OK, so I caved and ordered a 12mm ‘One of a Kind Penis Spine and Plug’ based on all the great reviews. Since I had ordered other right sized 12mm plugs from CG I felt confidant the 12mm spine would be a perfect fit – and it is: both length and width. When I opened the package it, of course, looked absolutely HUGE – but I cleaned it up and inserted anyway. The bottom ball required a small push to pop in so, too, the top cylinder. The ring, which looked too big, fit perfectly but the curve at the top, based upon extended wear, has to be modified. Because of the large diameter of the spine top to bottom, plus its very substantial weight and the diameter of the ring, Mr Happy looks ready to go all the time. Even with wearing briefs and proper fitting pants the bits and pieces show an extremely robust low hanging profile without any manipulation. The good news is probably due to the smaller size of the exit hole the post pee drip requires a lot less shaking of the dew from the lily than it does when wearing a torpedo. I really like the length although after 4 days straight I am still getting used to needing to adjust Mr Happy from time to time as well as refreshing the lube every other day. I am also getting used to using a bit less pressure when peeing: too much pressure creates an unusual but interesting sensation. Thanks CG: works for me! What’s next?
Update: Had to discontinue continuously wearing the Spine at 5 days. Not having adjusted the curve caused the ring to create some top side chafing. Now just about all healed up. Almost ready to get out the pliers and work on the spine. Missing it every day.

Awesome Review by Handsinlthr

Got my 10-13 hollow last Saturday and totally loving it. Please let me know when you perfect a 11-14 or 12-15 hollow, I want one of each. As other reviewers suggest, one a bit longer?

Ambitious Review by Woodman

This was a bit ambitious for someone who had never toyed with this before.
Nice workmanship but I will have to wait to find out how nice...

The boyfriend and I enjoyed it

Great product! Review by J

As with any new toy it took a little while to stretch enough to fit this in my penis. Nice, the ridges and end ball is nice. The gland ring is little too large. May I suggest a ring size of 3/4 and 7/8 inch. Smaller rings would be great to hold it in and enhance sensation when erect.

Great little high-quality piece! Review by C+

Being a deep sounder, I usually don't bother with plugs, but this one intrigued me because of the available maximum size of the hollow one, which is 13mm, my current stretch for deep sounds.
This toy is a pleasure to take in if you can handle 13mm at the glans stricture. Just lube it and hold it in place and let gravity do its remorseless and deeply pleasurable thing. The sensation of being slowly penetrated lets you feel each of the bumps at the stricture and their slow movement down your urethra is worth every penny, believe me. The retainer ring is a good fit for me but YMMV.

I found that with the curl down and remaining flaccid, the toy will actually penetrate to the prostate with sufficient patient and gentle encouragement. That was painless, but do not try this if you are not intimately familiar with your deeper anatomy. You could definitely do yourself a disservice if you don't know what you're doing.

Kudos to Chain Gang once again for the excellent finish and craftsmanship which is typical of all their stainless steel toys. I should know because I have literally pounds of their stainless toys.

Now, if we can just talk Russ into making a 12 inch version of this....please give it some thought, Russ. I'd buy it in a heartbeat and to hell with the currency exchange difference.

Now that I have stretched enough for it to fit, I'm having a great time with this plug.

good Review by Tippy

It is good quality. Fast shipping. Good product but for me I would like it about 3 inches longer.

Great product Review by DE

I have the 12mm hollow and 11mm solid. The hollow was a bit too much because I had never used anything like this before. So I got the smaller one t work up with success. It causes a pretty powerful flow when properly stimulated, if you know what I mean. However, it does get tiresome due to its length after awhile so I don't wear it as long as some of the other products I own. All in all, a good item to let go with.

One of a kind Review by Silver

My 13mm hollow spine and plug arrived on Saturday, got it all cleaned up, and then slide it home. What a feeling to have it go in and the weight of it is perfect. The ring locks it in so it will not fall out. I have been wearing it pretty much no-stop since cleaning it up. Chain gang you have done an outstanding job on this one. You have not disappointed me on any of the items I have gotten from you. As others have stated the quality is very good, it is very smooth and the fit is perfect.

Weighty. Review by Chris

Love the weight. Stays in well. Like smaller bumps in the middle when going in or out.

Great feelings... Review by Luc

I received my 11mm solid Penis Spine and Plug two days ago and I already experienced my first 24h non-stop and my first night with it... what a feeling to wake up while enjoying a hughe morning erection! Initially the glans ring was a bit too wide for me so I replaced it by a tighter one and I slightly adjusted the base of the loop towards the shaft. The quality of this plug is very good, no sharp edges at all which results in a very comfortable fit while remaining very present. The shape of the loop makes it very easy to attach a small electrical wire, and in combination with one of my ballstretchers this plug is therefore also perfect for great Electro sex.

Finally I Have it all in, GREAT. Review by The Doger

I have had the ONE OF A KIND for a year now and with a lot of streching excercises
I managed to insert it all after adjusting the loop that holds the glands ring.Now my smaller Penis Plugs will be a let down.

A nice surprise Review by Ron

The quality of these items is amazing. This item is at the maximum diameter for me.
I ordered it that way. I almost could not get it started but once I got the initial wide
point in the rest of it was smooth sailing. I had more difficulty getting the end tip of it in and really had to work on it but it was worth it. The glans ring was a bit small for me but I found that once that I got the end of it locked in (due to the end width) it was not going to be going anywhere. So no need for the glans ring. The very small exit point for the fluids is cleverly place but a bit small. It is noticeably smaller than the fluids entry point.

Another Quality Piece from Chain Gang Review by Mike T

Once again you have exceeded my expectations. A quality piece that fits and look beautiful. Gland ring is the perfect size. This is not a piece for the first timers. You will need to work your way up to the 11mm diameter and length. Well worth the effort.

(Posted on 6/15/16)

Love the feel of this. Great product Review by Scott

Love this. Bought both the solid and the hollow. Solid slides right in. Just a little tight when fully inserted. Needed to adjust the bend at the end to fit more comfortably. The hollow one is a little larger and i have only been able to get it started with the first ball. Still working with it though. Can't wait til i am able to hold this one all the way in. Great quality on both pieces.

Fantastic Toy - well made Review by Lawrence

Love wearing this especially overnight. Intense morning errection. Could be a little longer and the head ring could be a little smaller for a tighter fit. However with my Ampallang piercing that helps to keep the plug in place. All in all it's perfect.

I ordered the solid option.

Awesome Review by QL

It was a very unique feeling when the tip finally made the initial plunge in. Everything that followed was just as intense.

An epiphany Review by Kenneth

You might think, as I did, that a hollow device is necessary for long term wear. However, per a previous review from "slave friedemann", I went for the solid version of this.

You can indeed (if you find 10mm a 'pop' fit) pee around this.

The other problem with long term wear is going deeper than 1/4 to 1/2 inch deeper than the penis is long. A review from 'slave' titled 'Superb!' for the "Flexible Penis Plug" details this... basically what happens to me with long hollow devices is that the urethral lining 'bunches up' into the hole at the tip, and movement back and forth tears the lining. You get blood, and to prevent a possibility of stricture, you can't use the device.

This piece has a beautiful round at the tip, if you get the solid. It does not ever harm me despite its length.


If you do deep penetration, get solid and look for a proper round at the tip. If you go hollow, stay in the penis proper and look for a smooth lateral profile. If necessary, chop off the long plugs with a Dremel and use patience in re-finishing the tip.

I have over a dozen plugs, and these two reviews and experience with the unique shape of the 'spine' have combined so that I finally know what's really going on.

I also love the large 'bump' just below the bend on this- it pops in and helps retention and feeling.

Great toy Review by Pumpdaddy

Just got it this week. My first toy ever. It went in all the way first time. I left it in about 3 hrs. Then it slipped out. Had it in 3 times first week. Feels great. What can I do to keep it from slipping out?

Bigger Than I Thought Review by Richard

Quality is great but bigger that I thought. I'm using a sounding set to increase my acceptance of this device.

Awesome Review by Wild William

I have had my spine for a little while, had to adjust it a bit, I have never been able to get it totally in with the ring over my glans until tonight. OMG this is the most feeling to have it all the way in. Chain Gang you guys rock.

(Posted on 11/13/15)


Wonderful piece that I have had some challenges with to enlarge my urethral canal so as to allow it to fit snugly but comfortably. This is a LARGE Piece of Penis Jewelry and worth all the time I had to take to install it.

(Posted on 7/25/15)

Great item Review by Brolls

I was a little worried when I got the plug. But what a pleasure it is. I got some bleeding the first two times I inserted it. I love the feeling and having a simi erection while the plug is inserted. It is well worth the the price and what a pleasure. I can use it while doing electro stimulation. Another exciting pleasure.

Size Review by Sam

I have the king penis spine today and feels awesome!! Feels like it is the way to my postate, but it's not. Getting a little bit of postate discharge , which is fine. Great feeling when walking around, not so much when sitting. All in all a great piece of jewelry. Planning on wearing it quite often.

(Posted on 5/27/15)

Size Review by Sinep

Wow, just got this and didn't know how it was going to fit, but no problem. With a little lube it went right in,had a little trouble the half inch or so. The diameter was larger than expected and the length was longer, but got it in with no problem. The feeling is awesome and I'm wearing it with my PA jewelry . That a sight they are together !!!! Can't wait to get to a nude beach with these new toys! Need to try!

Daunting machine! Review by Guy

Wow, what a machine! Great quality. But much larger diameter than I ever want to push into my piss hole. I want a pleasurable sensation, but I'm not into extremes. I'll reorder something more "moderate." I just hope I can find one with the longer length like this one.

Superb! Review by slave friedemann

The best toy i have ever experienced. Believe it or not, peeing is no problem around the solid Spine & Plug!

(Posted on 4/11/15)

Awesome Review by William

I Posted when I first got the spine and hadn't been able to get it in at that time. Well I was playing around with it the other night when the tip of it finally went in. Before I realized it, it had already slipped three quarters of the way in. Still haven't gotten it all the way yet, but I know it will be soon. I do have to say that when I shot my load, that was the most intense orgasm I have ever felt in my life. When the tip did go in there was a small amount of pain and a few drops of blood but nothing serious. I will be using it again tonight and hopefully I'll be able to get it all in so I can start wearing it more often. Great product CG. Love it.

The ultimate to date Review by Deep Bob

I use urethral sounds so this is a slide fit. Walking around the office provides an incredible internal massage! I like the weight. Unfortunately the hole on the plus sits inside the tip of my penis, so peeing is a little splashy. I'm ordering a smaller ring, the plug wouldn't fall out but I like a tighter fit around the glans. Chain Gang has the BEST customer service, I'm a frequent flyer.

(Posted on 3/12/15)

Great product Review by sneaky pete

I bought two penis sounds at the same time as a beginner (first time user as well).

I purchased the Penis Spine and Plug as a solid piece and the Flexible Ziro Penis Plug and Glans Ring as well in the hollow version. Love both products.

The Flexible Ziro is a nice product but the glands ring is very small. Difficult to get on and almost impossible to remove. Like the product and works as stated.

The Penis Spine is my favorite and looks good when I wear it. The glands ring is tight and stays in place but is comfortable enough to wear all day. My only issue is it is a bit short. I would love to see the product be about one inch longer so that it would fit properly.

Both products are well made and a good value.

Don't forget that you can get replacement rings for your particular size here

Sexy, Love the look and craftmanship Review by MOOBS

Found out 10mm is a little big for me and now I am looking for a urethral stretcher... a 9mm or 9.5mm would work perfect. Love the weight and feel of the Penis Spine and Plug. I can't wait to wear it after some stretching.

(Posted on 2/26/15)

High Quality Review by William

I'm like another person, it is a lot bigger than you think. Right now, I can just get the tip of it in, but that's it. I will get this in but it will take time. Found though the ring is exactly the right size for my glans. All in all, I like it, but I'll be patient until I can get it in all the way.

(Posted on 2/12/15)

Very big Review by john

This will do Review by Ned Pepper

Thanks Chain Gang. You have made my day for many days to come.(pun intended)Although I bought two plugs this one is the best. Just lucky I guess this fits like it was made for me. Not going to get tired of this anytime soon. You are a great company to deal with and you will be hearing from me again. Fair warning. You will have a hard time doing any better than you already have done. I look forward to my next purchase. Thanks again.
