马来西亚采购需求：壁球发球机

I'm looking for a squash ball machine that meets some specific requirements for our facility. Ideally, it should offer adjustable speed settings to cater to different skill levels, allowing both beginners and advanced players to benefit from tailored practice sessions. Additionally, a compact design is preferred, making it easy to store and move around as needed. Furthermore, I would appreciate details on the machine's durability, maintenance needs, and power supply options. If possible, please include any available features that enhance the training experience, such as remote control operation or programmable drills. Looking forward to your response with product specifications and pricing info. Thank you!
