Orbit Micro is the only source you will need for your project. If you require special third-party components that we do not have in our product line, we can procure and integrate them for you. There is no need to buy from multiple vendors to source different components, no need to pay multiple invoices, no need to pay for the shipping cost when buying from multiple vendors. You only need one vendor, Orbit Micro, we will source and procure additional third party components not traditionally apart of our product portfolio; in order to successfully fulfill a customer requirement. We will provide customer service and technical support for the whole system, even third party components. Why? Because we sold you an Orbit Micro System, and we stand by our systems and its entirety
