I purchased 2 of these and so far have ran for 25 hours with no issues. they run great in parallel and are quieter than my last Champions. oil change access panel could be a little bigger or this might be 5 stars. That is my only compliant, love the fact they hold 3.5 gallons of fuel for run time.
I bought the I-Jen 4500 a month ago, took a deer hunting. It ran for five straight days. Start it up beautifully. It ran quiet, a great value for money spent
i have had it for a week now doing great i have nothing bad to say it does what its suppose to without using a ton of gas while my solar is down on bad days
