Great little generator but the access door for the engine oil filler neck is too small and makes it very difficult to see without getting down on ur knees or tilting the unit to the side. A 1st year engineering student could do a better job of designing the access to the engine oil filler neck on the engine
The iGEN4500 came in after 4 days and opened it yestrday. Very well made and after following the instructions, it powered immediately. Easy to operate and after 4 hours turned is off. I am satisfied with it. I should have rated it 5 STARS but due to its weight, I only rated it 4 STARS. I will buy another one that I can just carry in and out of my Pick Up truck.
