Aug 2022 update: Purchased this 2-1/2 years ago. Wired it up to a 30-amp "most of the house" circuit. We just got power back from a 3-day outage due to a storm. Unit fired right up, ran about 10-hours before needing fuel, and kept us out of the dark for the whole time. It's noisy, but they all are, and the noise blended in with all the others in our neighborhood. Would still recommend.March 2020: Recently purchased the 12,000 watt version of this to replace our old 2,000 watt model. Did the limited assembly required (you need to buy the oil) and got it ready. We were lucky on the timing because last Monday, the power went out. This unit was needed actually 3 days after I finished installing it... and it delivered. Powered up all of the *necessary* things in the house. These things are noisy, but this one was actually quieter than the one we got rid of. It is also heavy; 240 pounds. Get help moving it until you put the wheels on it.
