I purchased the iGen 4500c to replace a generator that was stolen. It is easy to set up out of the box. You just need to add oil (included), connect the battery, add gas, turn the fuel valve to on, turn the rocker switch on and press the start button. It is really quiet and is easy to maneuver with the telescoping handle.
I purchased this to replace a stolen generator. After researching the options I decided on this model. It cranked right up with the push button electric start and is super quiet.
