The best feature is that it can run on either gasoline or propane, and you are able to switch between fuels without turning off the generator! This is great, especially during emergency situations where you do not know which fuel you will be able to get. Mine is very difficult to start with the button starter, unlike the experience of some others, it won't start at all using the kickback starter, and it backfires when it starts. But it runs, and produces power, which is the main point. It vibrates, and is loud, but it works. It arrived with some damage to the frame and a broken spark plug boot, and was shipped in a box with no padding at all. But it runs.
My husband loves the push start. He has used it only 6 different days so the review is limited. We use it for the fridge and TV. If you need a working clothes dryer buy a larger capacity. Also, The instructions say Output will be reduced approximately 3.5% for every 1000 feet above Sea Level so figure that into your computations.
