How I Test and Rate Chastity Devices

Last updated: August 2026

Most "reviews" of chastity cages are written by people who never held the device. Some of the biggest sites in this niche publish measurement tables they did not measure and photos they did not take. That is the gap this section exists to fill. I buy the device, put callipers on it, wear it, and write down what happened — including when the honest answer is "don't bother." Here is exactly how I do that, so you can judge whether my verdict is worth trusting.

I'm not a doctor and I have no clinical credentials. These reviews are my own experience with the units I own, not clinical or laboratory testing. Where I cite safety literature I cite it by name and link it. Always consult a healthcare provider for medical concerns, take a device off immediately if you lose sensation, and go to an emergency department early rather than late if you cannot remove one.

What I score, and why

Every review scores the same six core dimensions, in the same order, so you can put any two devices side by side and compare them on the same terms. A review may add an extra dimension when a device needs it, but these six are always present.

Hygiene & cleaning: How easily and thoroughly the device can be cleaned — on the body and off it. Ventilation, seam and weld finish, whether fluid and smegma get trapped, whether the material survives boiling or only a wipe-down. On something worn continuously for days at a time this is the dimension that decides whether the experience stays pleasant.
Safety: How predictable and forgiving the device is in real use: base-ring edge finish, pinch points at the gap, lock behaviour, and how quickly it comes off in a hurry. This is one wearer's experience with a single unit, not a lab test, a clinical finding or a regulatory determination.
Sizing accuracy: Whether the dimensions I measure with digital callipers match what the listing claims — internal diameter, tube length, gap, ring inner diameter and weight. Mislabelled sizing is a genuine safety issue, because the base ring is the part that carries the vascular risk.
Comfort over time: How the device behaves across a dated wear log rather than in the first hour — day 3, day 14 and day 30. Skin at the ring interface, sitting, sleeping, exercise, and anything that made the test end early.
Build quality: Materials, tolerances and finish, and how the device holds up across repeated wear and cleaning. Construction that degrades is a value problem first and a hygiene problem shortly after.
Value: Whether the actual experience justifies the price, and how it stacks up against the obvious alternatives at a similar or slightly higher cost.

Scores run from 1 to 5. A score is my judgment of the specific unit I bought, not a measurement that would hold for every unit off the line. Manufacturing tolerances vary, especially at the budget end, so treat a single score as one informed opinion, not a guarantee.

The five measurements, on every review

Every cage review carries the same five figures, taken by me, on the unit in the photographs, with digital callipers in millimetres to one decimal place. Three readings per dimension, median reported:

Internal diameter — inside the tube at its widest point.
Tube length — base of the tube to the tip, along the axis.
Gap — the space between ring and cage with the device assembled.
Ring inner diameter — for every ring supplied, not only the one I wear. The base ring is the part that carries the vascular risk, so it gets measured in full.
Weight in grams — assembled, on a kitchen scale, with the fitted ring named.

Each review shows these next to what the listing claims. Where a manufacturer rounds in its own favour, you will see it. If a dimension could not be measured, the table says so rather than borrowing a number from the listing — a figure on this site is either something I measured or something explicitly attributed to the manufacturer.

How I test

I own it and I wear it. No review is written from listing photos, spec sheets, or somebody else's review. If it is on this site, it has been on me.
A dated wear log. Devices are worn across a 30-day window with fixed checkpoints at day 3, day 14 and day 30, so reviews stay comparable. The log records skin at the ring interface, cleaning, sleep, sitting and exercise. If a test ended early, the log says when and why.
Cleaning the way the material allows. Steel gets boiled, resin and silicone get the treatment their material tolerates. A device that cannot be cleaned properly on the body — usually a ventilation or gap problem — takes the hit on the hygiene score.
Photographed myself. Every photo is of the actual unit I bought, on a neutral background, never manufacturer stock and never anatomy.

What I buy, and who pays

By default, I buy every device I review with my own money, and the review says so plainly. If a device is ever provided free by a seller or brand, the review states that clearly near the top, because a free device is a material connection you deserve to know about. A free unit never buys a better score.

Nothing here is monetised

This site currently earns nothing. There are no affiliate links, no coupon codes, no tracking tags, no sponsorships and no paid placements anywhere on it, including on these reviews. Retailers are named in plain text so you can find a device; there is no version of that link that pays me. If that ever changes, it will be disclosed on every affected page before the first link goes live, and the editorial policy will say so in writing.

Negative reviews, dates and corrections

A review section where everything scores well is a review section you cannot trust. If a device is poorly made, hard to clean, or genuinely risky in my experience, I say so, and I anchor every criticism to something I observed on the unit I own.

Dates on this site are real. A review shows when it was published and when it was last genuinely updated, and every substantive change is listed in a changelog at the bottom of the page. I do not re-date a page to make it look fresh.

If you make or sell a device I have reviewed and think I got a measurement or a fact wrong, I want to hear it. Email contact@chastitycageguide.com and I will re-measure. Verified errors are corrected promptly and noted in the changelog on the affected review, in line with the site's correction policy.
