Bought this as an emergency back up for a fridge or portable a/c unit. The break-in as suggested on-line is quite different from what the manual states. Did 2 oil changes at 20-30 min intervals adding a load after the first. Second one came out pretty clean. Filled for the third time and ran a few min before shutting down and putting away. I’ll keep a gallon of the engineered gas in there as it is supposed to last up to two years. I’ll do another oil change after I actually use it. First impression is it’s relatively quiet, especially on eco mode, and compact enough to store just about anywhere. Fires right up. So easy I’m sure, if needed, I could talk my wife through start up too…and that’s saying a lot!
