About Our Systems:All of our systems undergo a rigorous testing and verification process. After a thorough testing and diagnostic procedure, each individual system is put through a continuous 24 hour stress test. At the end of this 24 hour burn, the systems are once again run through testing and diagnostics before being thoroughly cleaned and ready for shipment. Each system is backed by a 3 year over the counter warranty.
