Rated 5 out of 5 by Durablility Great product worked non -stop during a 2 day outage February 3, 2015
Rated 5 out of 5 by Seems quite good at this point. Have only run a few tests in the first 3 days of owning. Time will tell as to reliability and durability. Price reasonable. Noise level is pretty high but placement is critical. and in our case not a significant issue. Looked at others, but this seemed to exhibit best combination of size,price,reputation,and warranty. So far so good. December 21, 2014
Rated 5 out of 5 by Great Generator Best deal and performance for the money hands down. Generator doing exactly what i needed it to do. December 9, 2014
Rated 5 out of 5 by power to spare I just purchased my Generac and I must say it has the power to run everything I need it to run. I ran a test to see how it would perform and I have no complaints whatsoever. I will recommend it to everyone I know! November 21, 2014
Rated 5 out of 5 by Better than the rest. After extensive research, IMO this unit has all the spec's I require to run my home in an emergency power outage. After Irene and Sandy leaving me out of power for a combined 25 days, I don't have to split wood any more. This unit was more than adequate for running the 240v essentials in my home, furnace, water pump, water heater and my son's fish tanks. I suggest getting a unit that is a little more than you need. This one is 50 amps, My new GP15,000E was a lot quieter than I expected and the idle switch is great, only runs engine to speed as power is required. Generac should do a DB sound test on these units and post the results as it would no doubt better persuade folks to purchase these portable generators. It should also come with 4 locking wheels.

Rated 5 out of 5 by very good value for the price. very easy to set up and started right up. only problem I found was trying to find out how much oil the motor holds. did not find it in the manual. put oil in and kept checking dipstick until it was full. that was the only flaw I can find with it.noise level is a lot less than the generator it is replacing. if you need a big generator I would recommend this one.

Rated 5 out of 5 by Best 15,000 watt generator for the price I looked all over and this is deffinetly the best generator for the money. You won't find a generator of this quality at a lower price. Took about 10 minutes to put everything together and I had the generator running in no time. The extra oil filter and air filter are a nice touch. Very pleased with my purchase. I expect this generator to give me many years of service and peace of mind. October 30, 2014
Rated 5 out of 5 by Has everything I need! This is an excellent generator for the price. Starting with the person that took my order, he answered every question I had and it took no time at all to get it ordered with a delivery date that was met! Assembly was a snap. It took no time at all! I put 4x4's under the frame then installed the axle brackets and the axle. The tires were just a bit wider than the pallet, so once the tires were installed, all I did was roll the generator off the pallet! It started up easily and all plugs put out the voltage that was labeled! I took it to my deer camp and ran the cabin without a hitch! It is a slight bit noisy, but if I have a choice of noise or no electricity, I will take the noise any time!! I have not run my house with it yet, but that is coming up soon. Living on the gulf coast, you never know when a hurricane will come in on you and I will be prepared!! At this point, I give this generator an A++ rating! Once I run the house on it, I will give an update! July 30, 2014
