I was concerned about any assembly required, there was no need. Very easy to put the wheels on, handle already attached. Put oil, and gas in the generator and it started right up.
This model has great features. Easy to set up. My only complaint is that is was very heavy and difficult for me to handle on my own before getting the wheels on it. It has a great pull bar. Got it for the hurricane seasons.
I bought this a month ago and so far so good. We used it once and it worked great. We are awaiting our electrician to hardwire a transfer switch to the house to make it easier and more efficient.
