Just bought this and have finished a break in procedure. Very easy to start and runs smoothly. Adjusts to load changes and performs as advertised. However, not so much with the noise level. Supposed to be 52 dbA at some un-specified operating condition. I measured 60 dbA 30' away and 65 dbA next to the generator while running with about 500 watt load in eco mode. Not what I would call "Extremely Quiet". Best noise level was inside home (windows & doors closed) was 46 dbA. That is what I would consider "Extremely Quiet". For emergency use OK because of the price, for camping not OK.
