After Hurricane Sally, I decided I needed a larger generator, and the dual-fuel feature on the IGen4500DF was especially attractive. The propane option, even though not quite as powerful as the gas, to me is much more convenient, easier to store, and safer. Easier to have 5 propane tanks around than 5 extremely flammable plastic gas containers. Starts and runs without a hitch, easy to understand controls, everything in the right place, powerful, quiet. What is there not to like??

Bought this today and ran it for four hours to break it in. It ran flawlessly and worked in the economy mode with no issues that were mentioned in the reviews I’ve read. This is a nice size to run everything in my house except for the dryer and electric stove.

Add oil, gas, push the button and you are off! I really thought at least one of the batteries would be dead or something but the unit's battery and that of the remote keyfob worked right out of the box. It's even wired for and comes with a battery tender! This is the simplest generator I have used and it is absolutely quiet enough to not disturb anyone!

I have completed the 5 hour break in period and the unit has performed well. The power is stable and the unit is very quiet. It picks up the load of my RV AC well when I first start it, but it has some problem after the unit has been running for awhile. I hope this will improve with usage.

I've only had it for 2 days but I'm already pleased with it. I thought we'd run out of fuel after a few hours of the AC running on it but it lasted all day, that was a nice surprise because our AC isn't exactly energy saving. The remote start/shut off works from 20-30 feet away as long as there's a clear line of sight, perhaps more but I haven't tested that yet. The handle and wheels were a nice touch for portability. Overall I think it was a good purchase for us.

after 11 months of storage, sitting in the garage, on the charger, run once a month for 10 minutes since first fueling, the starter has failed. never actually used the unit to provide power, but kept in a ready state. very upset customer. also, in an attempt to upload a video per this Westinghouse review page, youtube automatically classified my 37 second video a "short" and this URL type is not valid for upload to this review section. only standard antiquated youtube URL's can be uploaded here. 1 star all around.

Step 2 in the manual after connecting the battery is add the oil provided. The whole bottle. And what happens? A lot of it runs out of the generator all over my driveway because it didn't need the whole bottle. Then we have a features page in the manual which doesn't come close to matching the location of the features on the generator. And the instructions for paralleling inverter operation fail to state that if the generator has two black inputs (rather than 1 black and 1 red like the cable), then color coding on the cable doesn't matter. One can stumble into that information by going on-line by looking at pictures associated with the cable. The generator started up nicely using propane after pressing the on/off button and again very nicely using the remote. I didn't fire it up with gasoline yet, but when I do the gas will NOT contain any ethanol. I plugged the generator into a 50 amp power inlet box located outside by the main breaker (using the parallel cable and a 30 ft 50 amp generator cable after taking the central air and hot water heater off line and the results were very good. Had several computers and printers running, TV, refrigerator, microwave, a bunch of lights, and use of the garage door. I bought a second IGEN 4500 (gas unit as the DF units are sold within hours of receipt it seems) to use for parallel use with the DF unit. Haven't taken that unit out of box yet. I won't be able to use central air even running two units in parallel, but I will be able to run a wall rattler AC and perhaps use a burner on the stove if I manage other items carefully when a stove burner is on. The generator is very very quiet. The hardware is great; so what's the reason why the manual can't be good?

I just purchased this generator, and have only unpacked it. I must say the packaging was top drawer. Once I get it assembled, which shouldn't take long, and break it in, I'll complete an honest review. Love the many features this unit has to offer. Right now, I can only choose 4 stars because I have not run this equipment.

After a very long exhausting comparison of all the current generators out there and a very in-depth review of all the review websites that showcase the companies that have given them the most money... This is the very best generator spec for spec. It runs any fuel (including Natural Gas if you look up an easy conversion) It has both a battery and a pull start just in case your battery is low. It's quiet and has a remote. This generator packs all the features you need into an amazing package. Best of all in my opinion it is very frugal on both gasoline and propane. All this adds up to a fantastic generator...

I researched generators for quite a while before deciding on this one. The features that mattered to me the most were dual fuel, remote/push-button start, and the noise level. We have another inverter generator that we bought when we had a pop-up trailer, but we needed something with more power after purchasing a travel trailer with an AC and a microwave. Everything works so far, it's much quieter when running on propane. I also like that all the plugs and things on the control face have little covers/caps to keep out dust and water. One thing I wish it had was some kind of locking point where you could run a chain lock through it to secure it to something. I'll use the two top handles, but it looks like it only takes a small socket to unscrew the bolts that hold those handles on.
