You can use any suction cup toys you own with the machine through the suction cup adapter to achieve the effect of automatic thrust sex toys.You can also use the brown standard dildo alone or connect with an extension rod to expand the usage.The base is hollow and refillable. You can design the weight of the base yourself and fill it with water, steel balls or small stones to make the base stronger. At the same time, the hollow base is also more convenient to carry out. Adjust the tilt angle using the white screws in 2 positions. After filling the base with water, the weight reaches 2.6KG (5.7lb), making the machine more stable and the suction works better. Product Maintenance and Care: (1)Lubricant and condoms are essential. (2)Pay attention to the angle during use, and do not press the body's weight on the machine. (3)Continuous use should not exceed 60 minutes, allow the machine to rest for a few minutes to effectively cool the motor and extend its lifespan. How to Avoid Lag During Use? Stucking usually has three reasons: 1.Lack of lubrication: Sufficient water-soluble lubricant effectively reduces resistance and significantly improves the user experience. 2.Incorrect angle, body pressing against the machine's telescopic rod: The correct angle is crucial; otherwise, the telescopic rod cannot advance. Avoid exerting body weight downward. 3.Choosing too large anal attachment: In such cases, adequate lubrication and a suitable anal attachment are required.
