Primary option is to why I purchase this is because it was a dual fuel and being in the middle of nowhere Kansas means that if I'm out of gasoline I'm out of power in a storm. Was an elderly mother needing a mobility chair charged, oxygen, heat etc that is just a problem that I can't allow to rise. It may not have heard the whole house but it kept the freezers the refrigerator the heaters and her chair as well as a TV and several Wi-Fi units running without issue I love it
Tried it out and it started right up in all modes...manual, electric, and remote with both gas and Propane. Not nearly as loud as I expected it would be, which is nice.
This is a well built and designed machine. easy to set up, clear concise directions and well labeled ports, gauges and instrumentation. Easy to move with the wheels and the dual fuel option is wonderful. Runs like a top!
