Rated 5 out of 5 by from Great American made product Have a friend that has a Generac and raves about it all the time.Did some investigating and found that for the money you can't find a better more reliable unit.Come with its own cart,which is an option with most other units.The dial startup can't be any easier to use,starts with the first pull every time,and I have a very bad back but the unit started so easy I couldn't believe it,wish my push mower started this easy.

Rated 5 out of 5 by from Reliable Home backup generator I purchased the RS5500 generator to have on hand for bad winter storms and power outages. My area has a tendency to be without power for a day or two minimum when it does go out. I haven't had the opportunity to use it during an outage yet, however it was very easy to assemble out of the box and to get running. It fires up on the first pull and the dial makes it very easy to get going. I also found it surprisingly quiet compared to other portal generals I have been around. Can't wait to put it to use!

Rated 5 out of 5 by from A fantastic generator! I bought this generator (RS5500) for my parents as a gift after hurricane Maria in Puerto Rico. It was easy to set it up and to get running. Even my mom can start it without any problem. We are amazed that it can power up the entire home with great fuel consumption. Thank you Generac for making my family's life more easier after the event we are going through.

Rated 4 out of 5 by from Reliable and Fuel Efficient We put almost 200 hours on this unit during hurricane Irma. It always started on the first pull, and ran flawless the entire time. The only issue is the noise. I understand there is only so much that can be done in terms of sound, but if there was an accessory for an upgradeable muffler, I would gladly purchase it... or my neighbors might purchase it for me. I ended up parking cars around and in-between neighbors to try and help, but it's loud, no way around it.

Rated 5 out of 5 by from Very good piece of equipment Easy to set up, Instructions are very clear, simple starting and operation. Started on first pull and has done so ever since. Could have a little quieter exhaust tone but is not too bad. It saved two freezers during recent hurricane.

Rated 5 out of 5 by from great features Bought it for outage in case of hurricane. One of three in a row, that never affected us. But with an impending move to the mountains, it will be used.
