Rated 5 out of 5 by from Happy with choice Compared price and availability with several brands with similar output, including Harbor Freight Predator. Determined this appeared to be best overall value of generators in stock in my area when I was ready to purchase. Easy to set up and started on 2nd pull. All outlets worked and powered various test hookups as expected. Will now store away until we encounter a power outage. Hurricane season is here. Only complaint so far is the sound level...wife thinks it is too loud, but better than having no power.

Rated 5 out of 5 by from Well built generator After removing from the box and performing minor assembly and servicing per the manual, the engine fired on first pull. I checked the generator out, tested all sockets no problems at all. Very sturdy and I like the handle, makes it easy to move around. For me it was money well spent.

Rated 5 out of 5 by from Does the job I purchased this unit in a pinch due to a severe snow storm. This unit was able to run almost the entire house, including the well, hot water heater all lights,fridge, and sump pump, along with a few other odds and ends without a problem The unit is loud, like most generators of this size, but it is expected. The single dial made it easy for my wife to start while I was at work. Fuel consumption was all dependent on how many things were being powered up and seemed efficient. I ran the unit approximately 5 hours a day for a week. Unfortunately the hour meter stopped working before I even got the product registration verification so I am not sure the actual run time. I will be contacting Generac for the repair. Overall I would definitely recommend this product.
