Warranty on custom units: <p> For custom system configurations that have been specified by customer (ie that have not been engineered by 45 Drives), we warrant against defects in workmanship and parts that are specified by 45 Drives, for period of 1 year, or the part manufacturers' warranty, whichever is greater. Customers also have the option to purchase the extended 3 Year warranty, which covers the same items as previously mentioned. After assembly, 45 Drives will competently test to basic system functionality in advance of packaging and shipping. As we have not designed these systems, 45 Drives cannot warrant that they will be suitable for customer's intended purpose. </p>
