I have had this for 2 weeks now and very happy so far. Easy to assemble for two people out of the box. Started first time on both gas and propane. Power produced seems to be as expected, but I still have to hook it up to a transfer switch to see how it does powering the house.
Great price for the size of the unit. Enough power to provide the basics during an extended outage....refrigerator, water heater, dishwasher, master bedroom, internet modem, large room A/C unit. (Did not worry about powering central air). Simply plug into 50 amp connection outside, turn off the main breaker, hit the generator start button, flip the transfer switches from 'line' to 'gen' and you are in business!
I haven't run it under a load yet but so far everything is a described and it started quickly and easily and ran smoothly. The noisel level is moderate. With a little distance and some simple acoustical screening the sound is completely inoffensive from inside the house. The accessories included are fairly complete although a wrench for installation and removal of the gas line would have been handy since it is best to keep dedicated tools with the generator so you are never left short when the need to use the generator arises. Also the specs should include oil capacity (minor issue).
Bought it as a back up to power the house essentials. Propane option and remote start make it easy to operate. Started at the first try w/o any problem. I am happy with the purchase and would recommend it. appears to be a solid build as expected (i did a lot of research prior to making the purchase)
