The OTOUCH MACHO WORK 1 is a premium penis pump featuring a stepless suction function, allowing users to easily find their preferred pressure. The device includes a vacuum pressure indicator light that changes color based on the vacuum intensity (starting at blue and turning red at maximum pressure). A single press of the ''MACHO WORK'' button initiates suction, and pressing it again pauses the suction once the desired pressure is reached. The release button discharges the negative vacuum pressure. This pump has a transparent tube with both metric and imperial scales for clear visibility of results. The MACHO WORK 1 includes two sizes of seal rings (26cm and 32cm) for optimal comfort and pleasure. The penis pump is rechargeable. Use the MACHO WORK 1 for foreplay with a partner or for a unique solo experience.
