I purchase this receiver on line. Based on the evaluation it appeared to be an excellent deal for the price. Once received, it did not operate as the manufacturer had stated. It had electrical shorts, and just kept shutting off. I had to fight with customer service in order to get a replacement, well within the purchased warranty since I had only had the unit 3 days. First replacement was damaged on receipt, and finally after a heated debate with customer service I was finally shipped a functional unit. The aggravation involved far out weighted the value of the unit.
