Ordered my Generator online never had to talk with anyone. About 2 or 3 days later I was notified my order had been shipped. Freight company called the next day to verify address. They only had the ATS sent a email to Factory Pure. Got a reply right away. The next day the generator showed up. I like doing business with people who are concerned with there customers and don't wait 3 or 4 days to answer a email with customer concerns. Had a slight problem with installation, called Factory Pure got someone right away and he put me in touch with a factory tech who gave me the answers I needed. I would recommend Factory Pure to anyone looking for a generator or any other products they sale. Just had to put in a good word for Factory Pure .Now I bought a 17KV Cummins and the warehouse made a mistake and sent a 20KV. Factory Pure emailed me and ask if it would be alright. The Generator works great but the installation instructions are very vague took some time to figure out .
