Table Tennis Machine Training Machine (yuzapong pro) Power Model This table tennis machine was made by someone who loves table tennis. After repeated prototyping, we've created a table tennis training machine focused on simple and easy operation. It has a head-swinging function. Vertical angle adjustment (up and down) is also possible. Includes instruction manual. The three dial functions adjust ball speed, head-swinging motion, and ball feed. Compatible with 40mm balls and plastic balls; also usable with slightly smaller 39.5mm celluloid balls. By removing the launching device and changing the rotation direction, various types of balls (sidespin, underspin, etc.) can be set (freely adjustable from low speed to medium speed to high speed). The launching device has a "face," and the position of the "face" allows the player to judge topspin, underspin, etc. The ball passes through a pipe, and the 11th ball starts to be launched. You can adjust the speed of the rotating plate that feeds the balls, so you can enjoy the interval at which the balls come at your preferred timing! Machine size: Approximately 258mm depth, 390mm width, 255mm height. Holds 70 balls. After producing table tennis machines, we have a track record of 100 units or more, and we have completed a very good table tennis training machine. The product warranty is for a machine made by ourselves, and since there may be wear and tear on the motor, we will repair it free of charge in case of failure (shipping costs will be the responsibility of the customer). The product has been repeatedly tested for operation, so there may be some dirt or scratches. Please refrain from purchasing if you are concerned about this. The balls and table in the images are not included. Please ask if you have any questions. Thank you. Search for "yuzapong pro product description" for videos.
