Rated 4 out of 5 by Great Tool except for one issue Operation and transportation is well thought out. Overall the purchase was made over others due to the fact that this generator engine is specifically set-up for electrical generation. I'm not sure exactly what benefits this concept most, but it is reassuring.The issue is the fuel gauge. Mine does not function. still need to contact generac on this one, but it sure runs smooth!

Rated 5 out of 5 by Great generator! I have no complaints. I would get another if needed. March 16, 2015
Rated 5 out of 5 by awesome!!!! Ive had other generators in the past and none compare to the generac!! I use it for running my mig welder miller 252 and even in 5/8 steel its unstoppable! If you want quality, a generac!!!! March 11, 2015
Rated 5 out of 5 by Easy to get up and running. Great for first time owners. When its cold outside and you have no electricity is no time for hard to follow instructions. Everything you need to get it running is in the box. The instructions are simple and to the point. I didn't even install the battery. I filled the engine with oil, put gas in the tank, took a quick look at start up instructions, and pulled the start rope once and had power. That's when I looked at it and thought, it also looks good. It was running in 15 minutes. OK so I put the wheels on the next morning.It ran for 24 hours, added gas once. If you need power quick this is IT. I already my home wired to hook up gen. so you will need that plan ahead. Very happy with my purchase. February 18, 2015
Rated 5 out of 5 by Heavy Duty Takes on heavy load with minimal recovery time. Runs all the necessities, electric start is really nice, and the LEDs on the control panel & load indicator are really nice. February 15, 2015
Rated 5 out of 5 by Generac is the best! It took a long time of thinking as to make a purchase of a genrator. But when I finally did, I only considered a Generac, because of its reputation. February 9, 2015
Rated 5 out of 5 by great generator at a good price it runs great right out the box. Only had to put on the wheels, front feet, and handle bar. Even though it said to fill with oil,[a quart of which was included in the box] it was already filled with oil, and the battery was already charged. It started immediately on the first try. Looks great too. Has great features and powerful enough to supply most of my homes electrical needs. I will be connecting to home using a manual transfer switch as suggested in the owner's manual .[don't try this on your own. My son is a licensed master electrician and has connected many generators to building electrical systems.] February 8, 2015
Rated 5 out of 5 by excellent product A friend of mine owned a electric motor rebuild shop and recommended the Generac generators, said they were the best in their field. February 1, 2015
