I'm interested in exploring options for coffee making vending machines for my business. Specifically, I'm looking for a machine that can handle high demand, is user-friendly, and offers a variety of coffee choices, including espresso and specialty drinks. It should also have a compact design to fit in limited space, along with features like an easy payment system and smart maintenance alerts. Additionally, I'd like to know about the maintenance requirements, warranty options, and any custom branding possibilities. If you have any models in mind that meet these criteria, please share details about their specifications, pricing, and lead time for delivery. It would also be great to understand the energy efficiency of the machines and if any additional features could enhance user experience. Looking forward to your response!
