Lightweight and great!, June 10, 2008

Received delivery of this generator on the day of a huge storm that swept through and knocked out power for 30 hours. This generator allowed me to pump out my full sump pit, keep my two fridges cold, and had the TV and fan running (all happened at separate intervals). The best thing about this generator is how easy it is to use, and it's only 70 lbs. Fill up with gas and oil, switch the power on, gas on, choke, and pull. This generator is so quiet and has plenty of power to get you through a short term power outage. Dollar for watts, this is the best inverter generator out there. If I ever need a 30 amp hookup (ie. for a transfer switch connected to a house panel), I can buy another one of these generators and set up a parallel hookup. Also, since it's lightweight and quiet, I can use it for other purposes like camping. I also bought the hour meter and cover. This is a quality piece of equipment, made in Japan. Not the Harbor Freight special.
