Using this vibrating cock ring is easy. Just stretch it and place it on the penis. You can use the easy - touch silicone buttons to select from 10 different vibration functions. The ring is great for both solo play and with a partner. When using it with a partner, the ergonomic stimulator and nubbed teasers will target sensitive areas for added pleasure. For maintenance, make sure to clean it after each use with a mild soap and warm water since it's waterproof. Charge it using the USB charger for about 1 hour, and it will run for 50 minutes on high speed or 80 minutes on low speed. Keep it in a cool, dry place when not in use. Remember, if you have any health concerns, it's a good idea to consult a doctor before using the ring.
