COMPARISON GUIDE

The Vice™ receives substantially stronger buyer feedback than Holy Trainer, with roughly 4.5/5 from 178 reviews versus 2.2/5 from 8. Buyers generally praise The Vice™ for its secure anti-pullout design, long-term comfort once properly sized, discreet shipping, and especially responsive customer support when sizing or replacement issues arise.

The main criticisms concern occasional durability or pinching issues, but these are usually outweighed by the perceived reliability and service. By contrast, Holy Trainer is appreciated for being lightweight and discreet, yet reviews are dominated by complaints about lock failures, breakages, inconsistent quality, and poor customer support.

Overall, buyers tend to see Holy Trainer as more comfortable in theory, but The Vice™ as the safer, more dependable purchase.

Construction & Materials

• The Holy Trainer is made from molded resin/plastic and features a fully enclosed tube structure. It uses a solid curved ring system and locking mechanism integrated into the side or front or the device, depending on the version.
• The Vice™ uses a rigid cage and separate anatomical ring system with padlock assembly. The structure resists flexing and relies on modular components rather than a single molded body.

The key difference lies in structural rigidity and modularity.

Security & Durability

• The Holy Trainer relies on its enclosed tube design and tight ring fit to prevent escape. Because it is lightweight and slightly flexible, retention can vary depending on anatomy and sizing.
• The Vice™ is designed with retention geometry and rigid connection points. When properly sized, it is engineered to prevent removal without unlocking, focusing on positioning rather than excessive tightness.

Security in both cases depends heavily on correct sizing, but their structural approaches differ significantly.

Fit & Comfort

Holy Trainer models typically offer:

• One ring per kit
• Integrated barrel lock
• Adjustability primarily through ring selection
• No airflow

The Vice™ offers:

• Multiple ring diameters per kit
• Anti-Pullout technology
• Up to 64 fitting combinations in 1
• Open cage design with airflow

This modularity allows more anatomical alignment, reducing rotation and improving comfort during long-term wear. For occasional wear, both can be comfortable when properly fitted. For extended wear, airflow and structural stability often become more important factors.

Hygiene & Cleaning

Holy Trainer:

• Enclosed design
• Cleaning may require removal for thorough hygiene

The Vice™:

• Open cage structure
• Washable while locked
• Improved airflow

Keep in consideration that ventilation plays a significant role in long-term usability.
