Very quiet

Bought this unit to power electronic audio and video equipment. Works very well with low noice level and no interference or noice with sensitive equipment. Very satified!

Beautiful machine!

Starts on the first pull, runs as quiet as you could wish for, and is super reliable! This is great for camping and for days on the lake or out at the range.

Impossible to start

try to start every 3-5 weeks.this is the worse engine I have ever had. I have other small equip in my shed that starts after 2-4 pulls after sitting for a year. Regret purchasing

Not great

I bought it in January 15. I have only been able to start it twice. Neither time when I wanted to use it. I have another one of these that has worked fine for several years. This one is at a warranty repair shop and has been there over a month now.

Generac

Bought at Menards used for the first time 30 days after and it would shut down when any load was applied, had to get it serviced not replaced. Works fine now but would have preferred a new one not waiting 4 weeks fir a repair

Nice and quiet, nice features

Impressed by the operation and features of the unit, especially the load indicator and fuel usage as load increases.
