I just opened the box last night, folowwed the instructions. Put in the oil, hooked up the battery, put some gas in it, maybe a gallon for the break in. Turned on the battery power, pushed the start button and VOILA. This thing just fired up with no hickups. Runs smooth, checked the noise with my phone app, at 20 feet registered 43 db in eco mode, 46 on full power. You can't beat that. I noticed other people were complaining about rust at the gas tube and scratches on the unit. I had none of those. The unit is spotless, no scratches no rust. I ran it for 2 hours on eco mode, now I'm gonna change the oil. And of course the remote is the icing on the cake. This will be able to power my 24' travel trailer or back up my home. I have 3 Champion generators, a 4000 watt and two 2000 wats and they're great but this W estinghouse igen 4500 beats them all.
