Dual fuel capability of this generator was a big selling point to me. I didn't want to have to continuously refill it with gasoline. Propane burns cleaner and with a couple 100# cylinders it'll run for days, not hours!
My friend suggested that I purchase this generator, b/c he had one and I'm pleased with it. I haven't had to use it yet thankfully, because we've not had severe power outages. But I feel good just knowing I have it ready and on stand by.
I had the WGen 7500 DF and just upgraded to the WGen9500DF, I had nothing but great luck with the 7500, reason for the upgrade is I needed the 50amp outlet plug to run my central AC which I haven't setup yet with softstart. I have 3 of the Westinghouse inverter iGen 2500 for myself and family members and have had great luck with Westinghouse products. Will update the review once I get my AC situation sorted out
