Rated 5 out of 5 by from WOW! Single pull and immediate start-up Extremely easy to assemble. Adding oil and gas was quick and easy. Owner's Manual is spot on from Assembly through startup to maintenance. Extremely satisfied with the buying experience and the obvious quality of this product. The wife is especially satisfied and truly at ease with how the product runs and works with the necessary appliances in our home. We feel much more prepared for any natural disaster in our Florida home.

Rated 5 out of 5 by from Great Generator The setup was simple with easy to follow instructions. Once setup was complete, it fired right up. When the power went out during a hurricane the generator had no problems running the refrigerator and some other small items. It is a great generator for the money and does exactly what it is supposed to do.

Rated 5 out of 5 by from Heavy Duty This thing is built like a tank! I am impressed by the size of the frame and the quality of the build. As advertised it is quite easy to start and run. The only thing that I would change would be to add a fuel cutoff so the carb could be run dry for storage. Not a deal breaker though.

Rated 5 out of 5 by from Very well made and easy to maintain This unit is replacing a 14 year old gen. I was shocked to find that most of the replacement parts for the other unit are unavailable. Generac has been around for quit a while and have a great reputation for service and dependability. I got it home, took about 30 minutes to get it ready. It fired up first pull and ran for about an hour under load for testing. No problems working great.

Rated 5 out of 5 by from Solid generator. So far so good. Right out of the box theRS5500 is impressive. Fit and finish is impeccable. The unit is heavy for sure but it's not a toy so I expected that. After putting the oil in and adding gas the power dial made starting quite simple. What a great idea to put the choke, run and gas shutoff in one convenient dial. Once the generator was warmed up a little I plugged in some light loads and the tone of the engine never changed. I plan to test it further by plugging in a big refrigerator/freezer to see how it handles a bigger load. I have every confidence this Generac will be up to that task as well.

Rated 5 out of 5 by from Unit starts easy and holds the load This RS5500 unit runs great and easy start. Unit keeps up with the demand you put on it. Never stop or bogged down with power demand. Would recommend this to everyone.

Rated 5 out of 5 by from Good value. The Generator was very easy to assemble and prepare for operation. It started quickly and easily and ran smooth and surprisingly quiet. The included cable is a big boost in the value.
