I haven't needed to run this long-term yet, but in testing it, I found it to start up easily and runs very solid. It has good features and I can't imagine needing more power.
I ran the generator with a small load just to test it about a week after I received it and all seems good so far. It started up easily and it ran well. I was a bit disappointed to observe lots of bare paint (appears to be scraped) on the underside of the frame during assembly. Also threads on the frame for one of the wheels appeared to have been cross threaded at some point so it took some significant effort on my part to get the axle threaded properly. Hopefully this product will make up for poor initial assembly quality with reliable functionality for many years...
