The Strong One cock ring allows you to explore exciting vibrations alone or with a partner via the app control, whether you’re both in the same room or not. The design of the top piece is slightly curved and even, to hit as wide a surface as possible so that the intensity can be easily adjusted. 
The vibrations of the cock ring can stimulate the shaft and scrotum, and help to give a bigger, harder, and longer-lasting erection for even longer-lasting play. During intercourse, the head itself will also stimulate your partner, making orgasm easier to achieve. 
Connect it to the free Satisfyer Connect App, which is compatible with both Android and iOS. Here you can choose between different patterns or tailor your own vibrations, where you can transform either your partner's voice or your favorite song into vibrating rhythms.
If you would rather use it without the app, check the 10 built-in vibration patterns directly on the cock ring. Turn on the Power button and switch vibrations with a single click. 
The waterproof cock ring is made of body-friendly silicone, which gives it a silky soft surface. The inner diameter measures 2.5 cm and thanks to the stretchable material, it fits most sizes. 
It is rechargeable using the USB cable provided. A full charge takes 60 minutes and gives you up to 40 minutes of use time.
