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!
I haven't had to use it yet, but the unit is solid and appears well made. Assembly was simple, and came with a container of oil. Should be a good backup
