    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.

    Used it once so far, it did great!

    I got my iq5200df a couple of months ago and have used it once when we had a 16 hour power outage. I ran it on propane and it performed beautifully It allowed me to run 2 refrigerators and a freezer simultaneously and still watch tv. I'd unplug a refrigerator and then plug in the microwave or coffee maker, toaster or whatever so I had all I needed to have running when I needed it. The push button start instructions could be a little clearer but I figured that out. It seems like a top grade machine so far.

    I'm still glad I got a Generac generator

    I like Generac generators they are nice and quiet more or less some of the quietest on the market and then I got one of the 5200s and it is very quiet for its size but then it started having issues I had to take it to the shop a couple of times but Generac came through they actually gave me a new one was not expecting that but I'm glad they did so I still like Generac if you want to quiet generator that's not embarrassing to run then you need to get a Generac
