The Satisfyer Power Ring provides more stamina during lovemaking: The vibrating cock ring is pulled over the non-erect penis, which grows to a new size when erect thanks to the restricted blood flow. The cock ring stimulates both partners with 10 vibration programs that can be controlled intuitively with a button. It’s flexible and fits perfectly and excitingly close to your penis. The ring gives you a firmer erection and more stamina because of the restricted blood flow – while also delaying ejaculation.
