I was away on business during a huge ice storm throughout the Philadelphia suburban region.  My wife called and told me that we had no power... along with about 700k other people.  After reading several reviews, I ordered this WEN 3500W generator via Amazon Prime, shipped overnight.  I flew home the next morning and found the generator waiting in my driveway.Setup was simple.  You need to attach the wheels and handles, fill with oil, fill with gas, and start her up.  Started on the first pull despite sitting out in below freezing weather all day.  I let the generator warm up for about 5 minutes, plugged in a lamp to test, and everything worked as expected.  I then connected a power cord to my oil furnace (disconnecting power cables in junction box between furnace and circuit breaker panel), plugged it in to the generator, and restored heat to the house.Over the next few days, I also hooked up several lights, our alarm clocks, our FiOS equipment, laptops, and phone chargers.  No issues.  I did not try the 240V connection.  There is not enough power to run my electric dryer or water heater, so I found no real need for 240V.  I didn't run my fridge because it was already too late -- I didn't get the generator hooked up until about two days after we lost power -- but I would hook up the fridge in the future.The power company finally restored power to our house about 50 hours after we first hooked up the generator.  We ran for a total of 35 to 40 hours.Some other things you might be interested to know:- I used Mobil 1 10W30 and changed the oil after the first night.  I have an oil extractor to &#34;suck&#34; the oil out, but you could probably drain by tipping the generator on it's side.  An oil extractor is clean and easy.- The generator ran my oil furnace for over 10 hours on a single tank.  The tank was near empty when I refilled, but 10+ hours is more than I expected.- The tank is labeled 4 gallons, but it seems to only take about 2.5 gallons.  (The tank was near empty when I refilled, and it was only 2.5 gallons.)- Put Stabil in your gas can before filling the generator.  I use Stabil in my gas cans for my lawnmower, tractor, leaf blower, weed whacker, jet ski -- it really helps avoid carb issues.- Plug things in after the generator is running, and unplug things before you shut it down.  I don't know if I would have an issue if I left things plugged in, but I don't want to find out.- Buy a few extension cords.- Generator makes noise, but we were able to sleep without issue.  My wife commented that it wasn't as loud as she expected.- Get a carbon monoxide detector and put it in the room closest to the generator.  We had no issues.Bottom line: Three hundred bucks to bring my house back to life was money well spent.  We are ready for the next ice storm, hurricane, or whatever surprise happens next.  We can run our furnace and fridge.  We will have lights.  I am happy with this purchase and would buy again.  You get much more for your money buying for Amazon than buying from the local big box store when everyone else is looking for a generator.
