A replacement for a "dead" generator. Shipping and delivery was quick. Wheel install could use better directions - but it was not difficult. Unit started on first pull and continues to work well with each use. Fuel consumption seems within standard range. Unit is quiet enough for use in RV and camping areas.

Preparing For Power Outage

I bought this generator in anticipation of power outages in my area. Seems like twice a year, for days at a time, we lose power. I got it, put the oil in, put the gas in, and started it up. It tested very well. It's quieter than I expected but puts out good juice!

this little generator is a lifesaver.

got us through the blizzard after hurricane sandy. two days of running on just 16 gallons of gas, just be careful what size load you put on it. I definately recommend the 4000S if you are on a budget, but want a quality generator.

DuroMax xp4000

I purchesed 2 of these generators for my travel trailors, and I want to say that they are GREAT. They are not as quite as a 2000 watt honda, however we were very happy with how quite they were. I would buy these generators over again if I had another need for more. In case I didnt mention it my generators are the DuroMax xp 4000 Thank You C.E.C.

Worth Twice the Money

I bought this generator after a power outage that lasted for a week at my house. I ordered this on July 4th it was delivered on the 9th, 3 working days. I followed the instructions, put gas in the generator, and it started on the first pull. Its rated for 3300 watts and I plugged in a 1500watt heater and a circular saw, together about 3000 watts and the generator had no problems.
