I purchased this generator because the Generac generator that I had, shut down. The push rods smashed down enough to come out of the springs and not allow the valves to open and close. The only negative opinion that I have would be that the generator should come with the necessary plugs to plug into the generator. I had to go another night without power because by the time I got the generator running it was late and when I went to plug in the cord it had a different plug.

Our family bought 1 of these (as well as a few of other sizes) for back-up power after "Snowtober 2011" left us in the dark for 6 days. Our home has 2 heat pumps w/aux heat, and electric hot water. I wanted a unit that would be able to keep us warm, and this fit the bill. This is a BIG unit, upon delivery, 2 people are needed to assemble. We connected to the whole house through an interlock kit in the main panel and monitored load, we just used it for the first time after Sandy roared through- we ran our critical circuits as well as the hot water heater, TV/DVD, lighting and the stove. We ran each heat pump independantly due to load (10000 watt aux)The unit perforfmed flawlessly except for a resonating heat shield I had to creatively rectify. We put 95 hours on during a 5 day blackout. The sound level is tolerable for overnight use, overall very pleased with the quality, performance, ease of use (love the electric start!) and that they are Made in USA. We are electricians so we did all the work ourselves,

During the ice storm of 2013 our areas' power was out for 8 days. I borrowed my brothers Generac4500 and was impressed with it's ability to supply power for services of our rural property. When you are in the country and you loose power it includes you water supply and with horses it was essential that we had a constant and dependable power supply for this period. We have since purchased a Generac7500 with electric start and it is able to supply stable power for our whole house. We have used it recently when the power was out for a day and we never missed a beat.

Like so many others, going 7 1/2 days without power during the freak October Nor'easter SUCKED! I bought the GP7500E for back up power. Great unit! Easy assemble out of the box....was up and running in 15-20 minutes. We will never be without power. What a relief knowing we won't have to go throught that again! I recently had a friend who's an electrican install a 10 circuit transfer switch. This unit has plenty of juice to power everything we hooked up and then some. Hopefully we won't have to use it too often but, if it goes dark again.....we're ready! Thanks Generac

Haven't had a chance to run the house with it yet, but I'm sure it will make light work of it with no problem! The overall quality and appearance of this machine is very well put together. The only issue I had is that it took over 4 months to get it...I'm guessing it's probably production run intervals.

I purchased this for my mom after the recent hurricane. She’s in her 70s with medical issues and this unit has made her comfortable in her home. It’s running 4 ceiling fans and three 110 ac units plus the house lighting and it’s not even straining at all. Thanks for a great product.

This is a great product for the price.The generator starts easily and runs fairly quiet.The fuel tank is huge and i can get about 8 hours out of a tank.I gave it 4 stars for only one reason and that is because of the wheels.This generator is very heavy and they should have sealed bearings on the wheels because when you have to move it on grass it is hard to push or pull.

I would definitely recommend this generator to anyone who is in the market for back-up power when the need arises. We just recently bought ours, and I can say without hesitation that I wish we would have done it along time ago!! Great product, and a well made investment.

Bought the 6500 in 2015 after losing power for 5 days after a storm. I went with Generac because of the trusted name and reviews. Recently lost power in a winter storm for two days. This baby ran for 48 hours straight through a transfer switch and powered my heat, two refrigerators, three tv's, all my lights no problem! Best $800.00 i ever spent.

With three consecutive NorEaster's this past March, power outages were commonplace on Cape Cod. Tired of being with out power, I researched generator manufacturers and dealers. Deciding upon the GP 8000 was a good decision. Fuel efficient, fairly quiet, many options, and most importantly ease of use. I travel frequently and wanted my wife to comfortable running it if needed. Not being mechanically astute, she quickly grasped the concepts and was comfortable operating the generator. Definitely recommend.
