I'm reaching out to inquire about the tennis ball machine you manufacture. We are interested in understanding the different models and specifications you offer. Specifically, we would like to know the features, production capacity, and any customization options available for your machines. If you could provide detailed information, including pricing and lead times, that would be greatly appreciated. Additionally, it would be helpful to learn about the machine's maintenance requirements and warranty options. We're considering a bulk purchase and are keen on establishing a long-term partnership.
