Rated 1 out of 5 by from Received generator dead on arrival. Brand new, with a dangerous fuel leak. The fuel valve is junk. When calling Generac, I thought they would send me a new valve, but instead directed me to a rink a dink dealer. I will spend the $12 for a new valve, and in trade they get a 1 star review everywhere I can leave one, for their bad warranty, and sub par quality. I do not recommend this company to anyone. Very unhappy with my first purchase of a Generac. They do not deserve the good reviews they do have.

Rated 5 out of 5 by from Very dependable unit I purchased this in 2005 because of the hurricane Wilma, I live in Pompano Bch. FL. It has set in the garage for 12 years . I started it last year to check it and put it back. By the way it started right up no problem. Then along came Irma this year. I had pulled it out and got ready. I lost power Sunday and didn't get it back till the following Saturday. The generator ran flawless and I never shut it off. I kept the neighbors food. It ran my central ac, refrigerator, a wall ac,freezer,4 TVs,4 ceiling fans Water heater, pool pump, lights, microwave, boat lift and never stopped once. The best thing I've purchased. It sat along time but was there when I needed it. Thank you for a great product. My wife has 2 different forms of stage 4 cancer and we really needed this life saver. Wishing you all the best and hope we never need it again but if we do I know it will be there. Sincerely Pat

Rated 5 out of 5 by from GP15000E This generator and i have been through two hurracains Just before August 9, 2004 – August 15, 2004 I acquired the GP15000E for construction work that i was doing at the time. some of my co workers said that for just for me using portable power it was way overkill but hey i'm just that way. So the overkill came in handy when Hurricane Charley arrived. Charley was brutal, killed power every where. Lucky for me, overkill and I had a lot of Power to run. I was lucky my neighbor was an electrician because i was just going to run fans and and a fridge. he happened to be around to help. In exchange for him hooking Overkill directly to my house"s breaker box so we can run the air conditioner I let him and his wife and his two little babies bunk with us which he really appreciated and so did i for his service. It was a hot for those four days that we went with out regular power but Overkill was a great investment. Not only that i went through with Charley but also moved to Texas just in time for Hurricane Ike in September 1, 2008 – September 15, 2008. Went three days with out regular power on that deal. There has been a few storms since then that my trusty Overkill has pulled me through some power outages. I would recommend for anybody to have a Generator of some sort but i recommend Generac because so far i have not had any problems with my Overkill, I"m glad i have that tool in my war chest. As a matter of fact a storm blew through Huntsville Texas yesterday 3/24/2017 that knocked down trees on the power lines that left me once again without power for about 10 hrs. Lucky for me i have Overkill here to save the day. well that my story , hope this helps you out with your decision on what power to buy

Rated 5 out of 5 by from Very satisfied I cannot argue against Generac generators. For reliability, dependability and overall satisfaction I recommend getting yourself a Generic. Yes, Generacs' do cost a little more but you get what you pay for. However they are not the most expensive generator company. So, don't skimp on safety and comfort due to price. Go the extra mile and buy yourself a piece of mind. I bought myself a portable generator GP1500E to be sure I have what I need.
