I've had this unit for less than a month, but it started right up & I've used both 120v & 240v with no issues. My only complaint is that the unit isn't set up to idle when there's no, or minimal load.
I've had the unit six weeks. It assembled as expected. It started right up, first time and every time since. I ran it for the prescribed break-in period, then again 3-4 weeks later. We had not had a power outage in that time. That will be the true test. I'm glad I spent the extra money getting a electric start model, as I was not successful in starting it with the pull rope. (I imagine a younger person could pull that rope faster, and therefore get it going that way.) I am quite happy with my investment in keeping the basement dry!
