BlackMax 2100/1700 Inverter Genny

My local Sam's has a in store only special Markdown on these right now. Reg $549 now $299. I snagged one. It's a Homelight/Husky made unit. It ran for 11.5 hours on the first gal of fuel at 90% ECO and 10% ECO off pulling 300 watts for break in. Pulled a 1,624 watt shop heater for a little while no problem. A little louder than my 12 year old Honda eu2000 but by no means obtrusive. Decided to fog the $$$ Honda and save it for quieter camping and start using the BlackMax for noisy race weeks and the 2 year warrantee period.

Any one else have any luck with these? Impressions?
