So far it's working well. Push button/remote start is great. Run's well on both gas or propane. Have put a 5,000+ watt load on it without issue. Just a slight dip/return in RPM when a device is powered up. Only drawback is it's weight over 200 lbs and the plastic wheels are already showing signs of straining from the weight. When unboxed we discovered one of the top frame rails was bent. Not quite touching the gas tank. We accepted the generator with the damage because it did not affect the operability.
I have not owned this generator for very long, but it seems to run the way it is supposed to. It starts fine and runs on both gas and propane. I have not use the 220 V but I did check it with a voltmeter. The box initially had a dent in the side of it but not a single scratch on the generator.
Have not used much yet. Seems to run okay. Needs 2-3 attempts to start. 50 amp plug too close to wheel and difficult to plug into with stiffness of 50 amp wiring.
