Purchased several years ago for emergency power. I've used it here and there for portable power. This past weekend used it for the 1st time as an emergency generator. Filled it and it ran 9hours on 1/2 tank of fuel under load. I'm not kidding, 9hours. Super quiet and loads of power. Great investment

What a beast

The generator showed up on time but the truck could not get to my house because of the location. No problem neighbor helped get it to the house. Wheel kit on, oil in, gas in and it started right up. I put a load of a couple of electric heaters on it for a little bit then freezer and fridge. Never missed a beat. Great machine and can't wait for the power to go out for the real test. Only con is that it is not Propane but I can live with that. Thank you GFO for such a great product.

Great generator. Great price.

Great unit. Started right up. The only issue was that fed x called to say they were going to deliver it but I needed to unload it off the truck. I told them it was a residence and I had no way to lift the 220 pound pallet off the truck. They then said they would call the company and then get a lift gate truck to deliver it. They did the next day and the excellent driver used his pallet jack and put it in my driveway. Other than that this is a great unit from a great company.

Nice power house

Well I must say, this thing is a beast. I own a house with a 200 amp service,everything is electric. Well pump,septic pump, hot water tank, two refrigerators, computers and many more. The only thing it couldn't run was my electric furnace. If it was cold I would just make a fire. Electric start is great for my wife and kids. Starts every time and runtime on a tank with medium load will last all night. Highly recommended.

Generator Still Works Good After Almost 3 Years

The DuroMax 8500 Watt 16.0 Hp Gas Generator w/ Elect Start & Solid Wheel Kit has been a good generator. I have used it during power outages. I try to run it for 20 to 30 minutes two or three times a month between power outages. I have it hard wired to the house electrical panel with a manual transfer switch.
The generator is housed in a shed with an intake louver and exhaust fan.

Good one to look at

I ordered this unit the day of Super Storm Sandy and got it nexrt day, if that is even possible from CA to NJ in one day!!
Put oil in it, and gas, it fired up right away and we didnt turn it off for 14 days, it never gave us a hint of trouble
I would suggest to order it NOW, if your in the market, because waiting until you need it is Silly/stupid, and I would know.

Awesome Generator...Love it!!!

Bought it after Irene and ran it for 7 days during Sandy. It did an awesome job. I had a transfer switched installed with 10 breakers, it turned out to be the best thing I did. I was able to run 3/4 of my 2400 Sq foot house. Also the service is great, I called to ask them some questions and they answered them right away.

Thank you Generator Factory Outlet!!

Thank you guys!!

wow this is a great generator

bought it after Hurricane Sandy, Finally got to use it during the snow storm Nemo. No power 2 days. The temps went to 9 degrees. With the generator we had heat, freezer, TV and lights, it was great, price was fantastic. Best thing I did was buy it. Oh yes I also housed a couple relatives during the storm. Live in R.I. South shore.
