I bought this new around 1993 from a motorcycle dealership. It has thousands of hours on it. It is very quiet. 1000 watts. It has been used for many trips. It has run for a week straight 10 years straight at a local jeep/sand race here in town.
I put a smaller pulley on a squirrel cage blower out of old furnace so the generator could start it. It has run that blower for many many hours during camping trips and at the races. WE slept in front of the blower for years with the generator running 15' away. It is quiet. It has been a great value.
I still have it today and use it. I have let a friend borrow it for many years also. It just keeps on going. I exercise it a couple times a year and only store it with ethanol free gas in it. It has burned leaded race gas, unleaded gas from the gas station also.
