The Satisfyer Power Ring enhances stamina during lovemaking. This vibrating cock ring is placed over a non-erect penis, which increases in size when erect due to restricted blood flow. It offers 10 vibration programs that can be easily controlled with a button, stimulating both partners. The ring is flexible, fitting snugly and excitingly close to your penis, resulting in a firmer erection and increased stamina while also delaying ejaculation.
