Background Anyone who has read my previous review understands how I found chastity and the trials that began afterwards in attempting to find a device that would serve the needs of my Lady and myself. Disenchanted with the time and money spent to date I was reluctant to go down the path of yet another vendor but seeing no other options, elected to try again. My next try was through these various forums and seeing the posts of Mature Metal, apparently a one-man force who has been making custom chastity devices for several years. Looking through his album I was impressed with the prototypes and models displayed. Purveying the Mature Metal website I found a very professional portal that did a good job of displaying the small but refined product line. Even so, I elected to contact Mature Metal directly for more details. The first e-mail exchange I explained my situation thus far and my inexperience with chastity and devices. When specifically asking what device that he made that could possibly suit my needs, I was encouraged by the response: All things considered the price was significantly less than I'd spent previously -- reviews here were mostly positive, although lacking details -- I decided to take a risk. I ordered, as per the recommendation, a Watchful Mistress. I waffled on the ring -- oval or round -- but since the oval was supposedly more comfortable, elected to try that route. All orders are done online via the web form and from a pick list; there is no way to screw things up. Any special customizations would need to be handled on the side or in the comments box. By happenstance I mentioned to Mature Metal that it was too bad that I waited until the first week of October to finally place my order, as I had a special graduation and ritual coming up the next week. One where it would be nice to have the device in time for. You can imagine my surprise -- having waited six weeks for my previous device -- to be told that Mature Metal would have my new chastity device to me in six days. In actuality I believe I had it in had in five. This, I would find, is fairly normal for Mature Metal�s level of customer service. The device did arrive and I eagerly tried it out. Of course, as is my luck, there were problems. Oh well! First, the cage -- which again, I swear, I did not exaggerate my penis length! -- was too large. Flaccid my penis barely entered the �head� of the cage. Mature Metal indicated that this was not normal; the cage would have to be re-made and shortened by approximately 1/2�. Next, the 1 7/8� base ring was very uncomfortable to wear. While the ring/cage gap was a paltry 3/8� (!), the tightness at the base of the scrotum was just too tight. Even though I wear a 1 7/8� cock ring (round), the oval base ring of the Watchful Mistress was too tight. Turns out Mature Metal measures the width (across) of the ring as the base size. So my 1 7/8� oval ring was, in fact, 1 7/8� wide but only 1 3/4� �tall.� This was a problem. Returning the unit to Mature Metal for a fix, we discussed pullout, which I found fairly easy. This lead to a discussion of posts or pins inside the Watchful Mistress. After some extended discussion Mature Metal decided to create a hole on top of the unit to allow a pin to be inserted and locked in place. The ingenious portion of this would be that various interchangeable pins could be used. We discussed further types of pins and lengths. It seems that my unit was to be the prototype! (In fact, the first pictures posted online of the �anti-pullout system� are from my chastity device.) In addition two bars would be placed on the sides of the cage to prevent manipulation of the penis to defeat the pin. All of these changes took, at worst, two weeks to complete. Unit back in hand I was eager to try out the new pins. In fact they worked better than anticipated. Mature Metal and I had further discussion on how to create new pins. Unfortunately the oval ring was still too tight -- even after widening -- as my anatomy demands 1 7/8� vertical height in my ring. I can�t explain it. At this point I elected to order a separate circular ring by way to compensate Mature Metal for all the modifications he had done on my behalf. Watchful Mistress Design Unlike some other chastity devices the Watchful Mistress does not give you any room to grow. The philosophy is to prevent the penis from becoming erect, thus any stimulation. It�s a unique idea and I�m pleased to say that it works. I won�t lie -- it does get �tight� during a full on erection -- but because there�s really no where for the blood to go the penis does not become fully erect. This has a byproduct of making the device of a very small profile and not large at all. Speaking of size, the metal and welds are top-notch. The craftsmanship is something to behold. The device is polished to a high sheen, of medical-grade stainless steel. The base rings are modified cock rings (I assume) and the components are crisply designed. At any given point the thickness of the metal is only 1/16� and plenty strong. Sadly I lack a scale to weigh such a light device but suffice it to say that the lock weighs nearly as much as the device. The fully-rounded base rings are quite comfortable. A note, however: if you elect to go with the oval size I would recommend ordering one size larger. This is because Mature Metal measures the width and then �squishes� the height down. If you wear a 1 3/4� cock ring then order a 1 7/8� oval base ring, etc. If you plan to go with a round base ring then simply order the same size cock ring you wear. Notice the medium X-face pin inserted 1 7/8" oval on left, 1 7/8" round on right Comfort Comparing to my two CB-series devices the Watchful Mistress is an order of magnitude more comfortable to wear. I always became jealous of the stories where people would receive their first CB-6000S, open the package, and put it on for 24-hours straight. I could never do that; I was in agony within one hour of wear. Well, with the Watchful Mistress and the round base ring I literally can put the unit on out of the box and wear for 24 hours with no ill effects! It�s nothing short of a comfort miracle for me. For long-term wear and the use of the pins, there are some considerations to be made, however (covered below). Security The ring/cage gap of Mature Metal�s devices are absurdly small. The largest default size is 3/8�, ensuring that you won�t escape. When locked on, the Watchful Mistress cannot be removed. This is something that I cannot say for either my CB-series of devices or my Lori #2. This is, of course, a humbling and very submissive experience. I cannot discuss security without going into detail about the unique feature of Mature Metal�s devices, the �anti-pullout system (pins).� So, do they work? The answer is �it depends� but there are some other compelling features that make these pins worth ordering. First, the pins (currently) come in two sizes which I have affectionally called short and medium. The short pins have a shaft length of 3/8� and the medium 1/2�, not counting the heads. Left to right, Spike, X-head (short), X-head (medium), Flathead, Post The pins work by being inserted on top of the device, pressing down into the soft folds of the flaccid penis. The device is then fully-inserted onto the base ring and locked into place; the mounting post extends over the pin (locked in place) and prevents the pin from being removed. It�s quite simple. The penis molds around the pin and the sensation you receive depends on the pin. Some pins are better at preventing pullout than others, some pins provide more �stimulation� to the penis than others. Ultimately it depends what outcome you�re shooting for. View from rear with medium X-face pin inserted; yes, your cock goes in there with it! Of the five that I have, here is a description of each and their usefulness: Spike (short): This is my favorite pin, and the pin I am wearing now. The head is filed into a small spike, as per the name. The penis is literally impaled upon the spike. Flaccid you really cannot feel it. When the penis becomes erect, however, the spike presses down into the penis. When I feel the spike pressing down I cannot help but become more excited, which in turn makes me become even more hard, which in turn... Well, you get the idea. This pin is perfectly acceptable for long-term wear (if you can stand it) but doesn�t work too well with nocturnal erections. X-face (short): Stupid name but clever pin. This pin has a large �X� cut out across the top and a ring just under the tip of it. The angles of the cuts are such that the soft folds of the penis are easily caught in. In short, the �texture� of the X-face pulls the penis when it moves. Again, flaccid you�ll not even feel this pin in most cases. However if you try to pull your penis out of the Watchful Mistress it is akin to dragging your penis across sharp glass. I have done pullout with the short X-face in place but it wasn�t particularly pleasant. X-face (medium): As above but you will know this pin is there, even when flaccid. Going erect will be quite painful. Trying to pullout? Not recommended at all. Not recommended for long term wear unless you�re a bit of a pain-slut. Flathead (medium): Just like the head of a screwdriver, this pin doesn�t look very intimidating. Flaccid you�ll barely feel it, however during an erection this is the most painful pin of them all. Great for CBT or tease/denial. Not recommended for long-term wear or overnight with nocturnal erections. Post (medium): Nothing more than a 1/2� pin with a rounded head. Comfortable for normal wear, you will definitely feel it when erect. This pin does nothing to prevent pullout, however getting back in is something else entirely. Only one of these pins effectively prevents pullout (medium X-face); all the others are good for sensation play. However, the larger point is that with any of these pins in place once you pullout you will not be getting back in. So the chastity philosophy is slightly different here. You can get out once to defeat the device but you will be caught. This says nothing for the mental bondage of having the pins impaling your penis on a continual basis. In short, I love the idea. It gets the job done but best of all you have choices. Need long term wear? The post is fine. A tease/denial session? Put the spike in place. Has your boy displeased you or caught masturbating? Put in the X-face pin. One caveat is that the pin system is currently priced as a $100 add-on. This is overpriced in my opinion, for what is essentially a hole and some small pins. I feel something in the neighborhood of $50 is more reasonable (and worth it). Build Quality I previously spoke as to the design of the Watchful Mistress and the great job that Mature Metal has done, even down to the pins. My only area of complaint are some very small lack of attention to details. The ring/cage fitting holes (with a lock inserted) have quite a bit of play in them. In some cases the cage can swing from left to right increasing/decreasing your ring/cage gap by as much as 1/8�. In its neutral state the device has some bias, leaning noticeably to the left in my case. Fortunately it doesn�t effect security. I�d also go on to say that the play in the cage fitting and its ability to move with the body is a good feature. Just beware when ordering that if yours has too much play you may need to have adjustments made. Customer Service I can�t think of how to write this section without resorting to hyperbole. Mature Metal�s customer service is nothing short of amazing. Receiving that first device in a matter of days blew me away. Every alteration has taken roughly a week to process and at no point did I feel like I was a nuisance. It was a positive experience from beginning to end. Throughout this process, because I was helping prototype the new pin system, we would communicate several times a day. There�s no way I can think to improve upon his customer service. I was notified when the product shipped, returns were painless, etc. The gold standard. Intangibles Thus far I�ve covered a lot of different areas but perhaps the nicest component of this process is supporting someone who is an active participant of the chastity community. Sure, Mature Metal is a business but you end up working with someone who takes a personal interest in chastity and providing a top service for those seeking a premium chastity device. So much so that he wears his own products and actively is seeking ways to improve them. If all of that wasn�t enough his devices are of top quality, comfortable, secure, and inexpensive. Seriously, what�s left to discuss? If I had to find a negative it would be that some of Mature Metal�s pricing is a bit out of wack. My base device was $275 with another $75 for an alteration fee to remake the cage (which was too large by no fault of my own). I did not pay for the pin system but it is currently valued at $100. Overall that puts the cost of the Watchful Mistress at $450. (I also paid $45 for the additional round ring.) Too much? Maybe. But if this was my first purchase? Not even close. I�ve spent twice that on multiple devices prior to this that don�t work. Conclusion I waited until completing all my business with Mature Metal prior to writing this review. I received no compensation for doing so -- I never asked for the pins to be included free of charge; read into that what you will. So my review stands on the merits of the device. In short if you want a comfortable, well-designed, secure, and top-notch customer service then you should check out Mature Metal.
