Rated 5 out of 5 by from Immediate Fix We had power knocked out for nearly 12 hours, and the backup sump pump, along with several refrigerators were my main concerns, seeing we were looking at several more hours down. I did some quick research on the Generac RS5500, and it lived up to the reviews. I set it up in just a few minutes, pulled the starter, and boom--POWER! I added several more appliances, lights, etc (oh yeah, and my neighbor's too) and it never missed a beat! No fuss, no muss!

Rated 5 out of 5 by from Still good today Bought a Generac 23 yrs. ago. Still running strong. Gave it to my son so I bought another after bad weather rolled thru and knocked out power. Went and bought a bigger one. Got home, put oil and gas in. Started after 3 pulls and ran for almost 4 hrs. with no problems. Hope this one last as long. Also have a Generac pressure washer thats going great.

Rated 4 out of 5 by from Very simple and straight forward I bought this unit to replace a smaller aged generator that is used for emergency power for my home. The features of this generator give me peace of mind knowing that my wife can easily operate it if I am out of town for work. The only drawback is that it is slightly louder than I expected. When the power lines are down who really cares about noise, just as long as you have lights, right? Overall, I am satisfied with the purchase, and I am really pleased with the simplicity of the controls.

Rated 5 out of 5 by from This product is extremely easy to operate. This generator really is a great investment. Perfect to have as a back up around the house, or to power any kind of outdoor activities. I love it.

Rated 5 out of 5 by from Very dependable and easy to put into full operation We had a terrible storm in Washington State where 9 power poles snapped like twigs. We had just filled our fridge and freezer with food and meat and knew it would take a while to get power restored. My wife, during work went and chose this particular model, which was basically a God send as I read the easy to understand instructions on running the generator, put gas and oil in it, pulled rope once, and it was purring like a kitten. We ran 3 extension cords to keep from losing over $600 worth of food, had the TV for entertainment and also was able to make fresh coffee. Very dependable and easy to use machine, "Thank You" Generac!!

Rated 4 out of 5 by from Long cold power outage ran good Ran well in very cold conditions. I am not a fan of the 50 hour valve adjustment this requires disassembly and replacement of parts and service center costs for a new machine.
