While updating the chastity device reviews page, it dawned on me that I’ve never written a Watchful Mistress review for my workhorse Mature Metal chastity device. Since this is the only custom-made device I own at present, that’s inexcusable. So, I’m going to remedy that right now.

I’ve worn the device for almost five months now, so I feel well-positioned to give my opinion.

Intro

At the start, I can tell you unequivocally that there is no comparison to wearing a custom-made device and wearing a mass-manufactured, off-the-the-shelf one. It’s like comparing a Cadillac to a Chevrolet Spark. The Spark may get you from point A to point B, but the ride will not be nearly as enjoyable.

My Watchful Mistress, one of the five models currently offered by Mature Metal, looks like a work of art. It’s impossible to exaggerate the fine craftsmanship and quality that Mature Metal puts into their products. It’s lightweight, and it has a consistent gap all around, which I love.

Meet The Watchful Mistress

The Watchful Mistress is another standard ball-trapping device that comes in three parts.

1. Base ring
2. Open-style stainless-steel cage
3. Lock (Abus padlock or security screw)

Mature Metal offers base rings in fifteen sizes, from 1-1/4 inches up to 3-inches. You have a choice between round and the more ergonomic oval-shaped base rings.

I went with the round base rings. Besides ordering the size my measurements called for, I also invested in two extra base rings in 1/4-inches increments smaller. It turns out it was a good decision. While I can wear any of the rings with the device, the smallest ring I ordered fits me best. Double base rings are also available at an additional cost.

I really love how the Watchful Mistress fits me perfectly, both concerning length and cage inside diameter. The tip of my penis sits flush against the tip of the cage, making urination a less iffy proposition. I went with the 1-3/8 inches inside diameter, which feels perfect for me. My flaccid penis fills the cage with no extra space, but without any sensations of the cage feeling overly tight. With this cage, I have not once had a problem with overnight, spontaneous attempted erections.

You can select from fourteen different cage inside diameter measurements when ordering the Watchful Mistress—from 1-inch to 2-inch at 1/8-inch increments. You can order the cage in lengths from 1-1/2 inches up to 5-inches, with fifteen options offered at 1/4-inch increments.

Mature Metal offers two locking options—Abus padlock or security screw. Be aware that the Abus padlock has a larger diameter hasp than most comparable small padlocks. If you choose the padlock option, Mature Metal drills the hole in the connecting pin just a tiny bit larger than the lock’s hasp. As a result, it’s a tight fit. That means using another padlock you may have lying around won’t give you the same fit, and that can cause problems.

Frankly, I didn’t understand why they made the fit between the lock hasp and pinhole so tight. I first assumed it was to minimize the lock rattling around and the resultant noise you get with some steel devices. That may be part of the reason, but not all.

The way the lock fits tightly in the pinhole also helps keep the device in the proper position when worn by limiting the normal rotation to the left and right you get with most every ball trapping device with a round base ring. When you move or walk, sit or stand up, the base ring, and consequently, the entire device tends to turn a bit from on center. When I substituted a lock with a smaller hasp for the Abus, the device rotated far more readily than any other steel device I’ve worn. It turns so much it can actually get your scrotum in such a bind it can be majorly uncomfortable.

At the moment, I’m wearing the device with a plastic numbered lock since I have a long-distance keyholder and am experiencing the same problem I just described. It gets annoying because it can wake you at night when your scrotum gets all twisted up in the device. Also, every time you have the urge to urinate, you must first adjust the device to its proper position.

I don’t consider the excessive rotation problem a defect. It’s more that the device is designed for use with a particular lock. I expect the security screw provides the same function as the Abus lock though I’ve not tried that locking option. At any rate, the device simply doesn’t stay in the correct alignment if you try substituting some other padlock or a plastic lock for the Abus.

Fit

The fit of the Watchful Mistress is phenomenal, and the measurements are exactly what I ordered. My device has an inside diameter of 1-3/8 inches, a length of 2-1/4 inches, and a 3/8-inch ring to cage gap. You can order the device with a 1/4-inch, 3/8-inch, or 1/2-inch gap. Since there is no good way to measure yourself for the gap, Mature Metal recommends the 3/8-inch gap for most guys. But, if that turns out too tight, or not tight enough, you can send it back for an adjustment.

There is an excellent measuring guide at Mature Metal for all aspects that worked perfectly for me.

Comfort

When worn with the Abus lock, I find the Watchful Mistress satisfyingly comfortable. It is a stainless steel device, so you feel the weight, but this is the lightest weight steel device I’ve ever worn. It has a low profile and doesn’t produce a noticeable “chastity bump” with anything I’ve worn with it. It’s perfect for long-term wear. I expect I could wear the device indefinitely with no problems.

Security

The Watchful Mistress is as secure as any well-made ball trapping device. I haven’t tried to escape from mine while locked, but it feels plenty secure to satisfy me. It certainly won’t ever fall off of its own accord as long as you’ve got a correctly sized base ring and gap.

Hygiene

Hygiene, something I won’t compromise on, is another place the Watchful Mistress truly shines. The open design makes keeping things clean a snap. Using a handle-held shower head, I’m able to give the cage contents a very thorough cleaning. The other thing is the spacing of the bars at the end of the cage means urination isn’t a problem. As long as the device is aligned correctly, I can easily stand and pee normally while wearing this device. I give the device top ratings in the hygiene category.

Recommendations

Overall, the Watchful Mistress is a quality-made, hand-crafted device that won’t disappoint. I can give it my unreserved recommendation to those looking for a quality stainless steel chastity device. It performs its intended purpose like a champ and looks good while doing it. While I’ve always liked Mature Metal’s flagship model, the Jail Bird, I think the looks of the Watchful Mistress are a little more aesthetically pleasing, and it retails for only $50 more than the Jail Bird.

In the realm of custom-made, steel chastity devices, Mature Metal is one of the most affordable options. I also like the fact that I can send my device back anytime I want any modifications done. They can adjust every aspect of the device except for the internal diameter of the cage. So, make sure you get that measurement correct before ordering.

Beyond being a very satisfied customer, I have no other affiliation with Mature Metal. I purchased the reviewed device using my own funds, and this review represents my own honest opinions.
