Worked perfectly when we had a power outage on Christmas Day.

We bought this generator because of 3 day power outage we suffered through this past summer. We lost power on Christmas Day and the generator did all we expected and more. It ran 2 refrigerators, stand up freezer, and furnace. We had heat, tv, lights, garage door opener ,coffee maker and everything else we needed. Ran for over 12 hours on a tank of gas. I would recommend this product to anyone, just make sure you have the correct size for you needs.

Easy to use, reasonably priced, Gets the job done nicely!

I already had to use my generator, because the local substation near us was shut down for about eight hours. had it up and running in about 15 minutes and ran 80-90% of the house without interuptions. Very pleased with this generator! I would highly recommend this generator!

Worked great!

Living in a remote location in North Western PA. our power was always going out and with this years bitter cold I figured it was time to purchase a generator. After speaking with a lot of people in my situation and electricians as well as the local power company it was clear a Generac was the way to go. I purchased the GP8000E. The electric company hooked up a connector to my meter that fit my 220 plug. The first time I had to use it was awesome. I plugged it into the meter pushed the start button and it powered my entire house. The only draw back was the wheel bracket on the frame broke. so I had to drag it into place from my shed as apposed to free wheeling it. Still it was pretty quite and after 7 hours of use still had almost half of a tank. I'm sold.

Easy to use / Easy to set up

I had been looking at a generator for awhile and contemplated many different brands. For the price, wattage and most importantly, name brand quality, I found that Generac was the way to go. Spend the money and get the electric start. Save yourself the aggravation at using a pull start. Just push a button and rock n' roll. Upon first unboxing it, everything was zip tied together very neatly and it was well packaged. It wasn't so overdone that you spend hours cutting away zip ties like you do with your kids toys on Christmas morning. Cut a few of the zip ties and you are ready to connect the batter cables. The generator was SUPER easy to get set up. If you can use a wrench or socket set, then you are good to go. You don't have to be super handy at all to do it. The directions were very simple and easy to follow. A matter of securing the wheels to the frame with the axle and washers (Provided) and also securing the pulling handle to the frame. Other than connecting these bolts and two very small bolts for the batter connection, it was a snap and took only minutes to unbox and be fully ready to use. The generator comes with an initial package of oil and it's a matter of opening up the oil valve and pouring it in. Heck, I can do that. This unit is very heavy. So if you plan on wheeling it around your house, or you have an outlet on a further away side of your house, just remember that you may be trudging it through feet of snow, like I do in Maine. So just have a plan in place to have it put somewhere for awhile or the ability to wheel it around with ease. Overall, the generator just looks cool. The black and orange color is cool looking. Obviously not a requirement and individual tastes vary, but it looks like a well built machine and the colors pop. The Generac name is why I went with this one. From past experience of buying cheaper name "knockoffs" to save a few bucks, I have always had it come back to bite me. It's true that you get what you pay for. This unit was priced the same as the knockoffs, too... so why not go for quality, even if you pay just a tad more. But I was very pleased with the price point. LAST, and my ONLY complaint was that I thought the unit came with the L14-30R cord. It DOES NOT. So, if you plan on hooking it up to a 30amp power source, with the 4-prong outlet you will have to purchase the cord separate. Other than that, I am 100% please with the purchase and think you will be too. It powers everything in my house that I need.

Great Generator

[This review was collected as part of a promotion.] I received this item for free from Influenster in exchange for my honest review. This is an awesome generator! I love that it has wheels, this adds a lot of portability. I also love that you can power it with gasoline or propane, which is super versatile. It provides a lot of power, which gives me a lot of peace of mind.

great generator

Great generator for the price! easy set up. It also will be easy to maintain.Easy to start. just to see what i could run with it i put it through its paces. I ran 5 lights, 2 fans, 3 electric heaters, well pump, refrigerator, freezer, heat lamp, garage door opener. it ran all of it without any problem. I was bold enough to run all the above and turn on the hot water tank. now thats when the generator knew it had a load on it for sure. overall great product! its all i need if the power goes out. its even wife friendly.

good quality machine and good price

Just got generator today, it is replacing an older, smaller one of another brand. Put it together with no problems and it cranked right up and ran smooth. This will be for occasional use as a home backup generator. Looking forward to many years of service from it.

Oil Leak in 30 Hours

Purchased the unit the morning Sandy was to hit my area. The unit was very easy to set-up and operate. The only issue is that the unit has started to leak after only 30 hours of use. After speaking with a Generac rep from the 1-800 service number, I was told to operate the unit, check the oil every 4 hours and bring it in for service once power was restored. Not the reliability I was looking for, but overall it is still working. I hope the repair and warranty process runs smoother.

solid

heavy and durable. runs forever i would like to see someone try to start this with the recoil rope, though. if someone can actually do it they should probably be in the olympics or barnum and bailey's circus i tried it on fresh fuel and a hot engine ( right after shutting it down ), and there was NO CHANCE of this thing ever starting with the pull cord. keep the battery charged
