Holy Trainer receives mixed feedback on comfort, with a slight majority of users finding it satisfactory. Comments highlight its practicality and comfort for short-term use. In contrast, Mature Metal is praised for its comfort, with a higher positive sentiment, and users particularly appreciate the design of the Jailbird model for extended wear.
“First and foremost, the Holy Trainer 2 is really comfortable and practical.”
“I tried the Ryker version of the Holy Trainer (which latter I cannot afford) and found that although the base ring was a distinct improvement on the CR3000 series, the juxtaposition of the tube was…”
“Since March, I've been wearing the CB 6000s or the Holytrainer from V4 almost exclusively.”
“8, 2023 I love my jailbird..I have owned the cb3000 and 6000 and the jailbird is ten times better in every way…I have been in mine for 23 days straight now and it is very…”
“I think the flat bar has a lot more potential for comfort than the jailbird (and I love my Jailbird if that says anything).”
“I have been in a Mature Metal Jailbird for 4 years and I wear it all the time when practical which is about 95% of the time.”
Holy Trainer's security features are moderately well-received, with some users noting improvements in newer models. However, Mature Metal is rated more favorably in terms of security, with users expressing satisfaction with the Jailbird's secure fit and the effectiveness of its security screw.
“I'm a big Holy Trainer fan when the my subject is not locked with a PA style cage.”
“The Ht-v4 seems to be a lot more secure than any other device I've tried to this point.”
“Escape prevention devices: The escape-proof devices, such as those from TheVice, GatesofHell for the CB6000/3000, and AntiPullout for the HolyTrainer, all function similarly.”
“His and Hers Chastity I've been locked in a Jailbird for well over a month now and have not intentionally orgasmed in it yet.”
“I got my first security screw with my Mature Metal Jail Bird note: security screws aren’t simply Torx screws.”
“In my Jail Bird with its 3/8” 8 x 32 stainless steel security screw, a screw with no driver available – even a phone call to Mature Metal to get another would require my wife…”
Hygiene is a challenging aspect for Holy Trainer, as users report difficulties in cleaning while locked. On the other hand, Mature Metal excels in this area, with a significant majority of users praising the ease of cleaning, even without unlocking, which contributes to its long-term wearability.
“In the past, the Holy Trainer device I wore was great at helping me stay secure because the cage goes through and past the ring, but was hard to clean.”
“The holy trainer cages are not easily cleaned while locked.”
“Side note, holy trainer knockoffs are harder to clean.”
“Answer7: I LOVE both of the devices, but the Jailbird (mine has a double ring) is very easy to thoroughly clean in the shower so you could literally wear it forever with no hygiene problems.”
“In my cage, a custom jailbird from Mature Metal, I do not need to unlock to clean.”
“We really like the Jail Bird as its easy to keep clean without taking it off every couple of days, but we're thinking that I'm going to need something different moving forward.”
Holy Trainer's build quality receives a mixed response, with some appreciation for its bioresin material, but also some dissatisfaction with its design. Mature Metal, however, is highly regarded for its build quality, with users commending the use of stainless steel and custom sizing, resulting in a very positive perception.
“I've also worn the plastic ebay ht-v5 and I found it to be quite good as well, but I prefer it in stainless steel.”
“I do like holy trainer cages for the fact that they use bioresin, but don’t totally love the tube look.”
“The thing you bought is a knock-off of the original Holytrainer V2, except the original is made of resin.”
“Mature Metal makes their cages out of high-quality stainless steel, which results in no reactions on my end, and every single measurement on the cage is custom-sized to you.”
“Hey, that doesn’t look like a Mature Metal ring Now, this article isn’t going to cover all of the details of 3D printing or modeling but rather give you an idea if this is som”
“Mature Metal (my personal favorite) is a super popular stainless steel option with excellent customer service, over a decade of experience and known for being a great lo”

Mature Metal emerges as the preferred choice due to its superior ratings in comfort, security, hygiene, and build quality. Users consistently highlight the advantages of its custom-fit stainless steel design and the ease of maintenance. Despite Holy Trainer's reasonable performance, particularly in comfort, it does not match the overall user satisfaction seen with Mature Metal devices.
