Rated 5.0 out of 5.0 by Great Generator This is the first Generator I have bought and so far I am happy with the purchase! It was very easy to put together. It only took about 15 minutes from unpackaging to startup. It is a little loud, but not over bearing. I shut the power off to the house and started it up on the first pull! It ran great and most importantly it ran the jet pump, furnace, refridgerator, living room lights and TV, kitchen lights and bedroom lights and TV! Everything I needed to run! I used 2 15W energy saving bulbs in each room. One thing they should include is a funnel for the oil. Over all it is a great product! January 8, 2013
Rated 5.0 out of 5.0 by Solid and well built Very well built. Was just what I expected. Ran for 3 hours so far and didn't skip a beat. Started right up on the first pull. This generator is 3 times more powerful than my old generator of 35 years. Could not run the whole house on old generator during power outages. This generator will surely get us through with more comfort. Surprised at how quite it is. Not as noisy as my old generator. Large fuel tank will mean longer run time between fill ups, compared to my old generator. I Can't wait till the next power outage to give the generator a really good test. It is a little heavy but not bad to move around since it does have a handle and wheels. March 18, 2013
Rated 5.0 out of 5.0 by So Far, So Good! I got this generator 4 weeks ago and got my transfer switch wired up just in time for Hurricane Sandy. I lost power for 24 hours and ran the Generac for 10. The 6500 was more than enough to run my fridge, gas water heater, gas furnace, lights and outlets in select rooms with plenty of juice to spare. As a courtesy I powered 2 of my neighbors refrigerators as well. I was also happy with the noise level. I was expecting it to be much louder. I ran the generator in the shed with the doors open and fans running to keep airflowing. October 31, 2012
Rated 5.0 out of 5.0 by No Doubts, money well invested I am very satisfied with my purchase of my GP6500E generator. It was money well invested. The quality and performance of this Generac generator is great. The installation and startup directions were very easy to follow for someone like me that is not to keen on the mechanics of putting something together. The motor is not too noisy at all, we can barely hear that our generator is on at all when working. I will definitely recommend this product to all my family. I am getting ready to purchase a Generac Home Standby Generator in the next few months. July 5, 2015
Rated 5.0 out of 5.0 by Powers everything Great value for the price. Have used it 4 times since purchased in 2012. I use it to energize the entire power panel so we can use water (well), fridge, stove, lights and AC. It's a bit noisy, so this is the one improvement I would suggest. July 5, 2015
Rated 4.0 out of 5.0 by Life saver during power outage We was dealing with a major power outage, after looking at several other brands, I went with this brand and size, because everything I have heard, I trusted it. This unit was perfect, it provided power for my side by side fridge, and two upright freezers with plenty to spare. While others were sitting in the dark, we was sitting in a well lit living room eating supper. Love my new Generac generator. June 15, 2015
Rated 5.0 out of 5.0 by Best purchase I ever made !!! Straight off the skid, gas and oil added and my Generac fired on the first pull. Even my gf has no problem firing it up. We're doing major alterations on a cabin and use the generator at least 4 days per week. Surprising how long it runs on a tank of fuel. I ckeck it several times daily and swear somebody is sneaking gas into the tank. It's a bit noisy, but outside where that doesn't matter. Before retirement, I'd been in construction but never had the opportunity to use a generac. Those boys don't know what they're missing. I'm completely satisfied, and have already boasted about my great choice. When the work is complete, my Generac will be set up for back-up power. I feel secure knowing it can be counted on in a pinch !!! May 21, 2015
Rated 5.0 out of 5.0 by This Product has great power for the price advertised It ran my sump pump, refrigerator and lights with no problem. First pull start up on the first try. Excellent buy June 13, 2015
