Rated 4 out of 5 by A solid mid-level size generator for emergency use This generator arrived 2 days after Superstorm Sandy hit and left me without power. It took 30 minutes to unwrap it and put it together (attach the wheels, fill it with oil and gas). It fired right up on the first pull. With ease, it runs my refrigerator, a handful of lights, TV, cable box, modem, space heater and an occasional microwave use. It was averaging 12 hours of run time before needing to be refueled for the 96 straight hours of use before our power came back. It appears to be solidly built with high quality materials. Nothing felt flimsy. Changing the oil was a breeze. As others have noted, it is loud. For example, it is far louder than my 2 stage snow blower, and I quickly learned to wear ear protection when I am near it. But that's a small inconvenience compared with it's usefulness.

Rated 5 out of 5 by Perfectly fits my needs! We're in the middle of a power outage caused by a severe line of storms. I went out and bought this generator without doing any research whatsoever -- I just needed a generator! It hasn't let me down. I'm currently powering my fridge (and the neighbor's fridge & freezers), my computer/router/modem, lights, and various other small appliances with no issues at all. In fact I'm currently typing this review on my computer that's on generator power. Wish it had a wattage gauge and an estimated time to empty fuel on it but those are minor details. October 3, 2014
Rated 5 out of 5 by So far it seems to be a great generator. The generator arrived on time, was easy to set up. I added the oil, gas, and it started on about the 3rd pull. I ran it for a few hours with a few items hooked up, and it ran great. I will know more once I have to use it when the power goes out! August 12, 2014
Rated 5 out of 5 by Easy to assemble and works great Powers fridge, deep freezer, dryer and entertainment equipment no problem. Good bang for the buck. October 13, 2014
Rated 5 out of 5 by Excellent generator for the price I work on utility sized generators. Generac is one of the best. I purchased this one for backing up my home during outages, and may use it for other projects or outings. The generator was simple to set up and assemble. I recommend using lock nuts or thread lock on the bolts, since they tend to vibrate loose as stated in other reviews. Put oil and gas in and the unit started first pull. The unit is noisy, but quieter than the gas drive welder that I have used in the past. Tested it with a Shop Vac and it worked perfectly. One note, I have always been taught to close the fuel valve and allow the engine to run out of fuel, this keeps the carburetor from gumming up. I have never had to rebuild a carburetor on any of the small engines I have owned. September 15, 2014
