We were bombarded with a freak Oct. heavy snow storm. in the Northeast.When I heard the predictions, I learned from past experience you don't wait.The morning of the storm I purchased the generator at the stores' opening. Later that night when I came home, usually a 1/2 hour commute, it took me 2 hours, dogging downed trees and utility lines.I connected the generator, and for 6 days enjoyed having power for my furnace,sump pump,etc.The generator was easy to use. My wife even found it easier to start than our lawnmower. The only problem was after I used it for the hundred hours and had to change the oil, the plug was difficult to get off. This may have been tightened too hard from the store I purchased it from. However once I removed the plug, changing the oil was a breeze.Based on the dependability of this portable model, I'm looking into one of the permanant residential models.
