I rate this five stars as a penis enlarger and stamina increaser. This is designed to increase blood flow either before adult activities or increase your growth and stamina naturally over time. But is great as a titillator until climax.

This is an excellent product with all the features you'd want. At $50-60, it's a great value. Expected lifespan is 6 months to a year. It offers unique sensations and may help with stamina training.
