We bought this generator and loved the easy to use panel, and simple set up. The only problem we had was the enclosed battery leaked. We will need to get a new one, hopefully it will be covered by the warranty.
I've recently bought it, so can't say much about any problem might face during normal use. After connecting the battery (it came disconnected), adding oil, gasoline, I attempted to run it using the manual start without charging the battery but it did not start. After charging the battery for about 30 min, it ran with a push with very low noise level. It came with a remote start/stop which is a very convenient feature. So far so good.
