Product Parameter Output Voltage : DC 3-24VInput Voltage : 100 to 240VStroking Speed : 0 - 400 strokes/minutesTelescopic Distance : 4.5CMAdjustable Angles : 0 - 120degrees Telescopic Movement Distance : 4.5 CM（1.8 inches） Adjustable Angles from 0 to 120 degrees and more, and the metal stand is more durable. How to adjust the angle, please follow the steps below: 1. The angle of the machine can only become larger and larger, but cannot return. 2. Only when the machine is pulled to the maximum angle can the machine close the angle and open the angle again. 3. During the process of expanding the angle, the machine can be fixed at any angle and the angle of the machine can be adjusted in this way. Note: It slightly increases the difficulty of angle adjustment, but the bracket is more durable and the angle fixation is more stable. 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.
