The Todo Mío is a rechargeable vibrating ring for couples, designed for the penis and groin. It features 3 speeds and 7 vibration modes and is waterproof. It offers stronger and longer-lasting erections over time, as well as clitoral stimulation during penetration. To use it, place the Todo Mío at the base of the penis when it is semi-erect. The pressure exerted by the Todo Mío vibrating ring at the base of the penis prevents accumulated blood flow.
