We purchased a 1200SC/Silent Diesel Genset Generator from GenMAX Power Industrial Inc IT HAS NEVER WORKED it ran maybe two hours....Even after the second motor was sent to us. Mr Walter Wei is impossible to work with. He talks in circles to keep from giving you a refund. I filed a complaint with the BBB case number 90208931 to try and get a refund from this guy. Beware of this company they will SCAM you!!!Regards,Sue
