I have just opened the box and set it up. I was patient and careful, i.e. I followed RTFM and had no problems. I bought the dual fuel model because my purpose is to have it for emergency power backup. Turns out that increased thermal energy in the atmosphere creates violent wind storms that knock out power lines. Who could have predicted that? I don't want to use gasoline if possible since it will spoil in the tank if it's not used. The propane regulator connections were easy. The only issue is the small washer in the LPG line from the unit to the regulator is smaller than the fitting so it falls out. It seems like it could be a snug fit, but they wrapped the end of the hose in a plastic bag to avoid it being lost, which was a heads up. I left the hose connected to the regulator to avoid losing it in the future. Hooked up the battery and pressed the on button, and it started right up. I ran my basement dehumidifier for five hours to break in the motor per the instructions. It was less noisy than the neighbor's lawn mower so no big deal (i.e. no complaints from others in the house). No idea about longevity. Storing for long periods requires pulling the spark plug and putting oil into cylinders to avoid corrosion of the pistons. I plan to run it every month for a little while to power a blower or vacuum the car, which seems easier. I ran the dehumidifier and a blower, which was only 1/2 max power so it should be plenty to keep the refrigerator and the blower for the HVAC running in an emergency.

I bought this generator as a backup during outages. The generator seems to be stable with no tension fluctuation. The noise is extremely low: it is possible to even talk close to the generator. The only issue that I have: it is too difficult to remove the old oil, when you are changing the engine oil.

After several days of researching for a generator, I landed on this beast. I’m sure I don’t need this much power but I prefer to have more then less. Generator was easy to setup and even though its pretty heavy, having the arm to pickup up and wheel around makes it easy to move around.

So far I am very impressed. The apparent quality, fit and finish, documentation/manual, supplied accessories and operation all very satisfactory. I was especially impressed with the exploded views of the parts, parts list and the schematic which showed not only wire colors but also gauges. As a Electrical Engineer this quality of schematic is not common. Still in the break in period so I expect satisfactory performance and reliability.

Followed instructions and fired up just fine with electric start on propane fuel - ran for an hour to break in. Only issue was entire container of oil ended up exceeding capacity. Did seem to be a small amount of oil in there from factory so may need just less than the 0.6L capacity when initially filling.

Really happy with the generator, starts easily and is quieter than I was expecting. It’s super easy to move around with the telescopic handle. The oil plug is a bit difficult to get to when adding or checking oil but everything else about the generator is a pleasure.

I read a lot of great reviews on this generator. I like the fact that it has dual fuel options. I unboxed it and now have peace of mind that I can use gas or propane. I also liked the telescopic handle for easy movement and the remote control is a big plus.

I have only had this generator for a week and am so glad I purchased this quiet beast. Easy to start (just push a button!), Easy to move around (and it comes with the wheels telescoping handle already on) and is not too heavy. Just plug in the battery, add oil and gas or propane, and you are good to go. For the most part, I will be using the RV outlet (TT-30R); it also has two 15/20 amp outlets and two usb outlets. It is great on gas and being an inverter only uses what is needed for what you are powering. No problem running a heater or air conditioner, or just a few lights in my trailer. This generator is so quiet you know it is on because your lights or heater is on and not because you hear it running. I really like the date display that lets me knows my voltage, hours of use, running time left. This West. iGen 4500DF is well worth its cost.

I researched exhaustively and found exactly what I need in my iGen4500DF: dual fuel, inverter, fuel efficiency, and clean sine wave output. Reviews were high and I had to search to find it, but I got it and now I am ready to boondock with my camper or, more importantly, have power during the next ice storm.
