Holy Trainer Review – My Experience with this Brand New V3 Male Chastity Device

By: JC Ways

Like its predecessors, the Holy Trainer versions 1 and 2, the Holy Trainer V3 is made in Switzerland according to the highest standards. Every time I use this male chastity device, I imagine the Swiss Alps and Cuckoo Clocks that the manufacturers must’ve been surrounded by. The hills are alive with the sound of… nothing, actually. This cock cage is really quiet.In this Holy Trainer V3 review, I’m going to take a look at the pros and cons of this high-end cock cage, talk about my experience, and help you see if this is the right chastity sex toy for you.

Pros and Con​​​​​s

Pros and Cons - Holy Trainer V3

Though I do think that the Holy Trainer V3 is one of the best chastity device products on the market (spoiler), it is not without its flaws.


  • Made from 100% bio-sourced plastic resin – completely hypoallergenic
  • Plastic resin becomes softer at 36°C (96.8°F) so it molds to your cock in hot bath/shower
  • 25 different customizations – 5 tubes and 5 rings to mix & match
  • All tubes/rings are fully compatible with each other – design your perfect cock cage
  • “Magic lock” brass lock gets rid of noisy/clunky padlocks
  • Brass lock doesn’t rust and is safe for TSA
  • Smooth, ergonomic shape maximizes comfort and minimizes pinching at the base
  • Silent – doesn’t jangle around when walking
  • Comes with cute travel pouch included
  • No more spacers, pins, or padlocks needed
  • Comes in tiny Nano and Nub sizes for fans of small cages


  • Expensive, but worth it for the quality
  • Difficult to get on/off in my experience
  • No e-stim capabilities like some male chastity devices
  • Parts aren’t compatible with older versions of Holy Trainer
  • Hard to find (in high demand)
  • Included “user guide” is crap

For the most part, the Holy Trainer V3 beats its competitors and bests its previous versions. Many male chastity fans enjoy a tiny cock cage, and the geniuses at Holy Trainer have given you lots of smaller options to choose from, including the Nano and the Nub sizes. Overall, this is a solid chastity device ideal for experienced/intermediate users.

If you’re a fan of small cock cages, the Holy Trainer Nano has a penis tube length of 1.36 inches, while the Nub has a penis tube length of just 0.98 inches. I would only suggest buying the Nano or Nub if you’re well-experienced in penis locks.

Things to consider before buying the Holy Trainer V3 cock cage

Things to consider before buying the Holy Trainer V3 cock cage

Before splashing out on this cock cage, here are some things to take into consideration:

Do you want something easy to clean?

This product doesn’t have lots of holes/spaces like a metal cock cage, so it’s not easy to clean while keeping the Trainer on. Your best bet is to rinse warm water through it in the shower and use your fingers to get some mild antibacterial soap inside, rinsing it through again thoroughly.

Do you need discretion?

If you want a male chastity produce which is subtle and discreet, then the Holy Trainer is perfect for you. The Small, Nub, and Nano sizes are easy to hide under your pants for everyday wear, while the lack of an external padlock means that there is literally no noise this thing can make – it’s compact and completely silent.

Can you afford it?

The current price for the standard set direct from Holy Trainer themselves is $165 USD before postage and packaging. This makes it 15 dollars more expensive than the CB-6000 cock cage, one of its main competitors. However, the Holy Trainer has an overall better design to justify those 15 extra dollars.

Are you a voyeur?

Although transparent is the most popular choice, the product also comes in semi-transparent colors of purple, pink, and black. If you or your partner have voyeuristic tendencies, this toy is perfect for you. If you prefer to not see your locked-up penis, then perhaps go for something else.

Holy Trainer V3 Features and My Experience

Holy Trainer V3 Features and My Experience

The 3rd version of the Holy Trainer has many features and benefits not found in the other models of this game-changing cock cage. Let’s take a closer look:


When you’re putting on a chastity device, you want it to be the right shape and fit for your penis. Sadly, many cock cages are limited to a couple of one-size-fits-all scenarios, which is not ideal if your penis is below or above average in any way.The Holy Trainer V3 has 5 different penis sleeves (sometimes called a “sheath” or “tube”) and 5 different rings (the part which surrounds the shaft/balls) which you can combine. These are:Nub sleeve – 0.98 inches longNano sleeve – 1.36 inches longSmall sleeve – 1.75 inches longStandard sleeve – 2.14 inches longMaxi sleeve – 2.54 inches longRing sizes – 36mm, 40mm, 45mm, 50mm, 55mmThere are 25 different customization options of these rings and sheaths, so it’s easy to get a cock cage which is the right size for your penis.

There are websites like Mature Metal where you can order cock cages built to bespoke specifications, but the Holy Trainer V3 gives you a lot of customization options at a far cheaper price.


When in chastity, comfort is essential. No one wants to be locked up in a device which makes them feel awkward and uncomfortable. Luckily, the Holy Trainer V3 is incredibly comfortable, especially after taking a hot shower or bath while wearing it.You see, the plastic resin of this product becomes slightly softer at temperatures exceeding 36°C (96.8°F), so in a hot bath or shower, the Holy Trainer molds itself to the shape of your penis even more accurately. I found that it was particularly good in the bath – it’s literally submerged in hot water rather than just being drizzled with it.

A cock cage that molds to the shape of your cock… what more can we ask for?

This comfortable device is ergonomic and has a smooth design, helping to reduce the pinching you get with some other products. My only qualm was that I found I needed some water-based lube to properly get my dick inside – my cock head was getting stuck halfway inside the chamber beforehand.


I’m not very good at cleaning locked cock cages – I lack dexterity and fine motor skills at the best of times. Keeping that in mind, I’d say that the Holy Trainer is a bit difficult to clean whilst you’ve still got it on. The closed design blocks off large portions of your cock head from reach, so you kinda just have to rinse and hope for the best.If you take it off, however, it’s super easy to clean. Although the usual sex toy cleaning method of warm water and antibacterial soap should do the trick, the plastic resin is resistant to all solvents and detergents, so you might even get away with putting it in the dishwasher. Generally though, stick to the soap and water.Not we have to talk about peeing. If you want to keep this penis lock on while urinating, you’re gonna have some splashing. While there are 3 separate holes (including a large urethra hole) in the Holy Trainer, I personally found it difficult to pee through this without making a mess. I’d recommend sitting down when you pee, lady-style. 

Alas, there is no easy way to pee while wearing a cage around your dick. Quelle surprise.


If you want a male chastity toy that you can wear all day without being noticed, then the Holy Trainer V3 is a great shout. More experienced users will appreciate the smaller Nano and Nub sizes which make hiding the toy in your pants even easier. However, as a wearer of skinny jeans, I struggled with discretion.

Sometimes you just have to work your outfits around your cock cage.

Many of the best penis locking products make a shitload of noise due to their clunky metal padlocks, but this is not the case with the HolyTrainer. There are no clanky metal parts to make noise as you walk – the whole thing is plastic and the lock is safely tucked away. If your pants are baggy enough, no one will ever know a thing.


One of my favorite things about the HolyTrainer is how travel-friendly it is. First of all, they give you a gorgeous little carry case to keep it in, along with 2 keys for safekeeping. The carry case is brilliant for putting in your bag and traveling with, although it does say “Holy Trainer – Male Chastity Device” on the side, so maybe don’t leave it in plain view.As pointed out by Mr. S. Leather in their Holy Trainer V3 Review, the “magic lock” on this product is made from brass, so it doesn’t rust and it can pass through TSA airport security without setting off the metal detectors. I haven’t personally tried it, so I can’t confirm that, but looking at the product, I doubt it would arise any suspicion with TSA.

Extended wear

Many reviewers, including the renowned cock cage reviewer Denying Thumper, think that this new design of Holy Trainer makes it pretty ideal for long-term wear. Now, I haven’t worn this device for more than a few days, so I can’t personally comment on it, but the high level of customization and high-quality design all scream “long term” to me.The brass magic lock is also resistant to rusting, unlike some cheaper penis locks which can rust over long periods of time. If you’re going to wear chastity devices for extended periods of time, it’s crucial to make sure that they can last that long without the lock going rusty or stiff!

Putting it on

I won’t lie, I struggled to get this thing on and off my penis. I ended up using water-based lube to get my cock inside and then having a hot bath to let the plastic resin mold to my cock shape better.

I struggled trying to get this cage on while fighting back an erection. It’s so annoying. It’s like your dick knows what’s going on and wants one last boner.

Before using lube, I found that my dick would get stuck against the inside of the penis head chamber. I also had a couple of problems pinching the skin of my penis shaft when trying to slot the penis tube into the ring, but I imagine it’s the kind of thing you’d get better at with practice. I’d recommend reading up on how to put one of these devices on if you’re not familiar – the “user guide” it comes with is useless. It’s literally a single small page that doesn’t tell you anything about how to put the device on. I guess they just assume that people will know already.

If you want to know how to put on a chastity device, there are some (NSFW) YouTube videos that show you how to put on the Holy Trainer products. All versions of the Holy Trainer have basically the same assembly – it’s very simple.


Taking it off

I won’t lie – I struggled to get this thing off. I tried to turn the key in the lock and it was too stiff… it wouldn’t turn at all. My heart dropped into my stomach and out of my arse as I envisioned a trip to the hospital or a very open-minded locksmith. Luckily, I did manage to get it off eventually.Because there’s no padlock, it’s easy to forget which way to turn the key, and you’re a little scared of forcing it in the wrong direction. I can confirm that you turn it clockwise to lock it and counter-clockwise to unlock it. If you leave it on for a while, the magic lock can get a bit stiff. Just yank it counter-clockwise (without snapping the key) and you should be fine.

Other People’s Opinions

Other People’s Opinions - Holy Trainer

I’m just one man, what the hell do I know? As with all my reviews, here I take a few negative and positive comments from other users to see what people think. These comments are mainly taken from the r/Chastity subreddit and r/SissyChastity subreddit:

Sissy Chastity is a form of male chastity where men dress in women’s clothes, shave their body hair, and wear chastity devices until their keyholder (dom/master/top etc.) says they can unlock. Many chastity sissies use prostate massage to make themselves cum, as seen in the NSFW “cum from anal” subreddit.

“Having been in for 30 days now I can strongly recommend this device. It’s built really well, is very comfortable, and only slightly complicates bathroom things. I’d give it an 8/10.”u/lockedupinirvine“Bought a Holy Trainer V3 Nano for my friend before discovering the design flaw. It basically renders the cage useless. You can slip out easily and accidentally.”u/Developerv_“Overall my wife and I are really happy with the product. I’m deciding what our options are with a custom cage but for now this is an excellent option. I’d definitely recommend this cage for any larger guys who are looking for a non-custom cage.”u/tallchasteguy“Much tighter and better fit than the v2 small. It doesn’t allow you to get hard. The guards that push the cage away from the ring on the v2 seem to be stronger for this model. I ordered the 45mm ring and it’s a tighter fit. Overall, I love it so far.”u/tlahwmOverall, people love the comfort and convenience of the Holy Trainer V3, though I’ve seen many people complaining about the design flaw in the Nano which makes it very easy to escape. Of course, you can usually escape from any cock cage if you really want to, but the Nano makes it a little too easy. Perhaps try the Small or the Nub sizes instead.


Cum-clusion -Holy Trainer

Many cock cages can be uncomfortable, loud, and difficult to hide in your pants. However, the Holy Trainer V3 is a comfortable, silent, and discreet male chastity device which you can easily wear all day without raising an eyebrow (or a boner). There are 25 different size combinations, and they even give you a size specification guide to find the best fit for you.Interested in buying the HolyTrainer V3? Click HERE for the best price!
