I just received this unit. I assembled it (easy), I added oil (easy) and I started it up (easy) for a few minutes. I will run it again in a few days for longer and add a load or two. The tru test will be the next outage when I can run my well pump.
We just bought this after several recent storms. It was easy to assemble and get started. It is very heavy; an extended handle would have been nice to move it around.
