Start by attaching the adjustable knee strap comfortably around your leg. Place your penis into the soft, form-shaped cradle and secure it gently using the included medical-grade silicone cord.
Tension can be increased or decreased depending on your body position and comfort level. The entire setup can be worn under loose clothing, allowing you to move freely and discreetly during your daily routine.
To ensure hygiene and longevity, we recommend cleaning all parts of the device daily. Use warm water and mild, fragrance-free soap, then let the device air dry completely before storing.
Never use harsh chemicals or alcohol on silicone or fabric elements. For added skin protection, you may use a soft silicone sleeve underneath the strap.
We recommend starting with 1–2 hours daily for the first week to allow your body to adjust. Gradually increase wear time to 4–8 hours per day, depending on comfort and your routine.
Consistency is key. Long-term use over several months delivers the most noticeable gains in both length and girth.
