I've only used it a few times but this generator seems solidly built and has all the bells and whistles I can think of. Switching between fuel sources worked like a charm. I did notice one of my sets of LED lights flickered when under generator power, but some others (also LED) did not have that issue. From what I can tell this is normal with some sensitive devices on this type of generator so should use caution with computers etc. I'm happy with the purchase overall and it's good to know I can run just about anything in the house with the power it delivers.
We bought several months ago and now have a great appreciation for it’s “ready to go-ready to work” construction. It is easy to start and with dual fuels has really been a life saver. It is quieter than our previous unit. We love ours and expect to get many years of use out of it!
