I bought my WGen5300cv while preparing for hurricane season. My neighbor recommended it to me, he is able to run refrigerator, light,TV. Wheels make it easy to manage.
The assembly not very difficult. I did find the funnel they provided for adding the included oil a bit frustrating as it only allowed you to pour the oil at what seemed to be an unnecessarily slow rate. But that is a very minor thing and I'm nitpicking. After set up was complete, it started right up and ran like a top.
