I just purchased this generator for home backup protection. I live near Houston and we have hurricanes and flooding issues. Went through the setup process and it started on first try. I noticed two thing right away. It was quieter and lighter than expected for a unit with this power rating. After running it for an hour, I hooked up several items and it seem to handle them with ease. Only item in question was the fuel gauge. It did not register any change at all. At this point I am assuming it did not register because I only put a half a gallon of gas in the tank for testing purposes. Next time I'll fill the tank up completely and increase the load. I'll update this post should I have any additional observations at that time.I am pleased with what I have seen so far.
