Rated 4.7 out of 5 by 201reviewers.
Rated 5 out of 5 by The Power Came on Just Before We Fired It Up! We were into a two day power outage and the temperature was in the 20's. Called ahead and paid over the phone - picked Generac because of the name and quality.Drove 70 miles and picked it up and by the time I got home I was too tired to put it together. It got down to 13, but our propane stove kept us warm - put our food outside!Got the generator put together and the power came on! Took a break, added oil and cranked w/o gas to make sure everything was oiled good and it started! Filled with gas and started on the first crank. Plugged in 2 space heaters and the truck engine heater and let it run for an hour and a half to break it in for next time.Plugged in the battery charger and charged for 24 hours to make sure it is ready to go - really like the battery start feature! Great purchase for us - we have been wanting to get one.(Your program won't let me post a 4 X 6 photo.) December 28, 2015
Rated 5 out of 5 by Very happy with the GP6500 This generator ran perfectly and powered what we needed during our last ice storm. I have 1500 sq ft and we could run our water well, water heater and lights and receptacles. December 11, 2015

Rated 4 out of 5 by Nice generator Bought this for mainly pump water and freezer during power outage. Put it together and started on first pull. Ran great. Just a little loud. Loader than a lawnmower, but worth the money. Nice to have during those ice storms. Would of giving it 5 if it wasn't so loud. December 9, 2015
Rated 5 out of 5 by Very dependable Starts on the first pull when primed properly. It's been very useful and dependable and is very quiet for a large unit.It has helped me out on several occasions. Worth it's weight for sure. December 8, 2015

Rated 5 out of 5 by This product has a remarkable starting ability never had one problem I live in a single home with oil heat and during the winter I need something to run all of the major things in the house if my power is lost this generator for the price is the best purchase that I've ever made it starts every time on the first or second pull I never had a problem with the needing more power than it supplies and if I do overload the circuit The Breakers work and help me to be confident so that my family is not left in the dark December 3, 2015
