Holy Trainer Review: How Good Is this Chastity Device?

Holy Trainer’s new 2020 V4 design model is a great chastity device to have if you’re into that sort of play and are in a market for a good cock cage.

Holy Trainer

The Good

It has a great design and many different sizes to choose from, making it available for many different men.

The Not So Good

The circumference is the same for all sizes, which makes it more challenging to use for men who have thicker than average penises. 

The Bottom Line

It is a good quality chastity device, with many different options to choose from, from the color to the size of the ring and will be a good fit for many men. 

If you’re a big fan of chastity devices, just the way I’m, you know that it can be hard to choose the right fit. You need to pay attention to the sizing of the cage itself, the size of the ring, the material, and the lock. 

And of course, the price is always important. 

In this Holy Trainer review, I’ll discuss all the things you need to know about this device. Also, I’ll share my experience using it and whether I think it’s worth your money. 

Let’s jump in.

Introduction: The First Impressions

In today’s review, I’ll be focusing on the new 2020 design, V4 version.

There are many reviews online on the V3 version, which is the older one, and you can’t get it on the Holy Trainer website anymore, but many people are still looking for that version to buy. 

Now, there are not a lot of differences between these two models, just some slight design improvements. 

V4 has a sleeker design that looks a bit less visible when you’re wearing it, and it’s just overall sexier to look at.

Also, the ring is flatter and fits your penis a bit better, preventing it from sliding around, and it just fits the form of your penis better overall. 

Also, another thing that’s different with V4 from the V3 model is the color choices. V3 came in four different colors – black, clear, pink, and purple. V4 model comes in only three colors – black, clear, and baby pink. 

Holy Trainer V4 Overview

So, to start with, let’s take a look at some general specs of this device. 

Holy Trainer is a plastic cock cage that might not be as sexy as the stainless steel models, but it’s still great.

It is made out of the bio-based resin material, which is 100% natural and resistant to all detergents. 

So, even though it’s plastic, it’s still a very good quality device, and it weighs less than stainless-steel devices.

Holy Trainer comes in five different tube sizes: Nub, Nano, Small, Standart, and Maxi. They also offer five different ring sizes to fit your penis better. 

I’ll be talking about the standard size Holy Trainer today as that’s the one I have personally and tried for this review. 

As I’ve mentioned already, the V4 model has three different colors you can choose from – black, clear, and baby pink.

However, if these are boring for you and you want something more fun, Holy Trainer offers a custom option where you can choose from 20+ different colors for an extra $20. 

It might be worth it if you’re buying it as a gift or maybe want something more personalized.

Price, Where To Buy

Chastity devices are not the cheapest sex-toys to have. Holy Trainer is not an exception. 

All five models, no matter what size, cost $165, and the custom color option cost $185.

Now, it might seem like a lot, and you might want to go and get the cheapest option on Amazon instead.

But, I don’t recommend you do it as cock cage goes on to the most sensitive of all your body parts, and you want to make sure you’re using the good quality stuff. 

With Holy Trainer, you know you’re getting a device made from safe, high-quality materials that won’t cause the allergic reaction or any other negative experiences. 

So, when investing in a chastity device, it might be worth paying a higher price. 

You can also buy their tubes or rings separately for the V4 model as well as the locking sleeve with keys if you break or you lose them.

Keep in mind that you can’t interchange parts from the V3 model with the V4 model, so don’t waste your time. 

The tubes cost $98, and the rings cost $48 when you buy the parts separately.

Design, Features & Discreetness

The very great thing about the Holy Trainer V4 model is that it’s way more sleek and elegant looking than its predecessors. Even though it is made from plastic, it doesn’t look cheap. 

In my opinion, the lock for this device is very smart, and one of the main selling points.

Instead of having the lock outside, hanging around the tube, and the ring, it is integrated with the tube and looks very discreet. 

Not only does it look better integrated inside, but it also doesn’t make any sound like external locks do when they move around and hit the ring or the tube.

So, if you want to wear Holy Trainer in public, you don’t have to worry about your penis area attracting attention. 

Let’s briefly talk about the ring:

Many men who tried cock cages, always complain about the ring design and size.

It’s usually made like a perfect circle, but in real life, the part of the penis where the ring goes is not shaped like the perfect circle.

It’s wider than it is tall, and when the ring is a circle shape, your penis can slip, and it’s just not a comfortable experience. 

With the Holy Trainer V4 model ring, it is designed to be more compatible with men’s bodies and wider in the right place, instead of being the perfect circle.

So, if you were unhappy about other cock cages that had circle rings, it might be worth giving Holy Trainer a shot. 

If you’re one of those men who like to wear the cock cage for long periods of time and need to travel for work, you need something that is discreet and won’t attract attention at the airport’s security.

Holy Trainer is made out of plastic, not stainless steel, which makes it travel-friendly. 

In Use: Fit, Comfort & Security

My partner and I love playing with cock cages from time to time.

She finds it very attractive when she is in control of my pleasure, and I think it’s a turn-on to give her the power of my orgasms, so I was very excited to try Holy Trainer. 

The first thing I have to mention is that it comes in a very cool looking Holy Book box, so it makes it a good gift for someone special in your life.

I think it’s great that they pay so much attention to details, and it does make you laugh once you receive the product. 

Now, when I first got it on, my first impression was that it was quite comfortable

I liked that the ring fit my penis, and I got the right size for me (I ordered the Standard V4, with the 45 mm diameter). Also, it was pretty easy to get into, and the lock wasn’t a hassle. 

One thing that I wasn’t very impressed by was the set of keys for the lock.

Now, usually, a big part of the appeal of using cock cages is giving your partner the keys and giving away the right to your orgasm.

I actually like it when my partner has the keys with her, either on a chain or as a necklace, as it adds to the play when I can see it. It’s teasing, and it makes it more exciting. 

The set of keys that comes with this Holy Trainer is so long and big that my partner can’t really wear it around the house, so it’s kind of a bummer.

But of course, not the biggest issue and depends on your personal preferences. 

For the first time, I wore the Holy Trainer for four days, it wasn’t too uncomfortable to sleep with it or in the mornings, but you have to remember to pee sitting down as otherwise, you’ll pee everywhere.

I’ve learned this lesson the hard way.

How Easy To Clean & Ensure Hygiene?

I recommend taking the cock cage off and cleaning it at least once a week, preferably every three to four days to ensure that it’s clean.

It’s just going to be more comfortable for you, and you won’t get any uncomfortable rashes. 

The best would be to take it off entirely and wash yourself and the device before putting it on again, as it’s not open enough where you can simply wash it while wearing it.

Now, I didn’t find it uncomfortable, and I didn’t get blisters or anything of that sort, but you need to be careful as there is always the possibility of it as there are holes where your skin touches underwear.

Would I Recommend it? If so, to whom?

I personally would recommend this cock cage. It is good quality, sleek design has an integrated lock, and there are plenty of colors to choose from. 

I know the price point of $165 might seem very high for a device like this, but as I’ve mentioned before, you really need to be careful and get only the best quality stuff as it will be close to the most sensitive part of your body. 

However it might be a bit of stretch to buy this as a first cock cage. There is a good alternative – Oxy Shop makes a lot more affordable stainless steel or custom (3D printed cages). For example, this steel cage costs only $40 and you can still adjust the main ring size.

Who is it for?

  • Men who want something sexy and sleek looking, but don’t want the heavy stainless steel options. 
  • Men who are traveling a lot for work and want something that’s discreet.

Who is it not for?

  • Men who are not sure whether they like that type of stuff as it might be costly to buy it, and you would be better off with cheaper alternatives for that. 

What do Other People Think About It?

I’ve looked at what other people on the internet are saying about this cock cage, and I wanted to share my best finds with you. 

Here is a great video review where you can see the Holy Trainer more up close:

What men on Reddit are saying:

“I received my v4 about 3 days ago. I started in a v2 and eventually a v3. I’m usually locked for 3-5 days between cleaning with a day out after being allowed to cum after 2-4 weeks.

The V4 solves the few problems I have had with the previous model. The base ring is flatter which prevents sliding down or out as well as prevents it from ‘flexing’ in the wrong way. The ‘tongue’ that the 3 has is much shorter, which means it’s more comfortable. Finally it’s more sleek, which means it less visible and in my KH opinion, sexier to look at.”


Reddit user

“It is genuine.

I am happy with it. Best fit out of the 3 models I have tried of it. The lock sticks out less this model than previous. The larger vent holes are nice as well.”


Reddit user

Are There Any Good Alternatives?

If this Holy Trainer V4 model doesn’t look very appealing to you, that’s OK. I have a few alternatives for you here. 

For example, are you looking for the first chaste period without breaking the bank?

Steel Cage By Oxy product shot

The best budget pick is Steel Cage by Oxy (currently running 20% sale so $40 only if you’re fast).

Oxy Shop creates and offers a high quality stainless steel cock cage for $good price while allowing to pick from 3 size main rings – 40mm, 45mm, 50mm.

It’s 48mm in length and 34mm in diameter, and has 3 air holes. It’s our new budget favorite.

Let’s take a look at some other more popular alternatives:

  • The Vice Chastity device is one of the most popular in the market and has a great design. It comes in three colors and has a more complex design with an outside lock. It cost anywhere between $120-$140, so it is a cheaper alternative. Get more information in the Vice Chastity review that we wrote.
  • CB6000 is another very popular chastity device that is of great quality and serves the purpose well. It also has the lock outside, it’s not integrated and comes in many different colors. It’s also a bit cheaper, coming in at around $150 for the device, so if you want to save a bit of money, it might be a good option. Learn more about it in our CB6000 review.

I also have a guide on the best chastity cage out there.

Conclusion: Final Thoughts

So, as you can see, Holy Trainer V4 is good quality, great design cock cage.

If you were looking for something to spice up your sex life, it might be worth giving it a go.

You might be surprised at how good the experience is. 

I hope you found this Holy Trainer V4 review useful, and it helped you make up your mind about whether you need this device in your life or not.
