    Tickled pink!! This generator is awesome!!

    Just bought this generator and I am so pleased. It is exactly as described. Runs my whole camper 13,500 BTU AC all lights etc. Runs nice and quiet. For the money I haven't seen a better product on the market. Comes with all you need to get started including a funnel to put the oil in the generator. I invited my neighbor over to check out my new generator for camping and he's already left to go order one online like I did. I'll come back and update this review after a few months of use and let you know if I am still happy with this generator. Thanks Generac for what I believe is going to be an awesome generator from what I have seen thus far.

    Ready for the Hurricane Season

    I am a very senior citizen and have limited strength. I purchased this electric start so I could easily start the generator when needed. Haven't needed it yet but it starts each time I test it. I had a manual start Generac for years that worked always when needed. Very good product.
