Just bought the 4500DF put in gas and oil and it fired right up. Still in the break in period so haven't used it a lot but it handles the load and runs quiet. I did see that the manual said the foam air filter should have oil on it so I checked it and it didn't. The set up instructions said nothing about doing this. When you get your generator CHECK THE AIR FILTER! So far I would recommend this generator as it runs good and has nice features.

Bought this as a backup to my gas hog non-inverter generator. Was very surprised with how quiet it is and how easy it is to setup. Added oil and gas, hooked up battery and it fired up almost immediately. Has started very quickly every time since. Hooked to house and verified it will run everything I need except 2 phase stuff for 15-20 hours, compared to old generator that used more gas and only ran 5-6 hours on 5 gallon tank. It's on the high weight side of what you might consider "portable" but I intend to take it camping as well. I wish the electronic display would come on with the switch instead of waiting until it is running. There is information such as amount of fuel that would be nice to read before starting. Other than that, great setup! Would recommend to friends.

I purchased this generator in February 2022, but did not get to test until late July. The generator started immediately with the electric starter and continued to start during initial testing. Worked on gasoline and on propane. I am pleased with the electric start as well as gasoline and properation operation. The only negative comment is that the generator is louder than my 20 year old inverter generator. ON THE SECOND (2nd) MANUAL START, SOMETHING BROKE ON THE MANUAL STARTER AND THE ROPE WOULD NOT RETRACE. THE GENERATOR IS DOWN WITH 3 FEET OF ROPE HANGING.

Only complaint is changing the oil. 14 dollar suction gun (looks like a grease gun) eliminated that issue. Its quiet, started on first pull out of the box. Ran 36 straight hours on a full tank + 3 gallons in sub zero weather. Electric start worked flawless.

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.

The quality of this inverter generator is outstanding. I'm able to run the AC on my Rockwood Mini Lite using only half of the output capacity. I ran this over for 40 hours+ two days on propane and it worked like a champ. 8 hours+ run time on a 20# cylinder. I love the fact I don't have to deal with gasoline but have it as an option in an emergency. Documentation is excellent. The pullout handle makes transporting the unit a breeze. The unit is extremely quiet, and the price is a bargain compared to competitors with similar features. I looked at a lot of generators before deciding on the Westinghouse unit, and wasn't disappointed. Highly Recommend!!!

I bought this to power a small sound system for outdoor events. Plenty of power and surprisingly quiet. Perfect out of the box. After connecting the battery adding the oil and connecting the propane tank, it started in the first try using the remote start key fob!

First time owning a generator. This unit is well labeled, instructions make sense, and was very easy to setup and operate. It is quite heavy but the extension handle makes moving the unit around easy enough. I will be teaching the wife how to get it all set up and have no concerns about her being able to operate it.

We purchased this generator primarily for camping. However, just after we received it, the grid power was shut off for fire safety and there was a problem with our batteries. So everything was dark. We hooked the generator up to the propane bottles and got it connected into our system. Ran the whole house load with no problems for exactly 24 hours, at which time our battery issue was corrected. We have since been camping with it and enjoy the remote start. We have an Airstream trailer which is all aluminum skin but the remote has enough power to work from anywhere inside. Very convenient.

I can't say enough about this full featured generator. I was looking for a lightweight generator that runs on propane and has enough power to run both a/c units in my travel trailer. This unit will do that on propane which is absolutely my fuel of choice for stability and convenience. I will eventually put soft starts in to make the transition a little smoother.This unit has every feature you could want including the ability to pair for a full 50 amp output.I opened the box, hooked up the battery,added the oil, connected the tank and it fired up in 2 seconds. This unit is every bit as quiet as generators costing more than twice as much. At 98 lbs, this old man can still load it by myself. I could go on all day about this unit,but if your in the market for a dual fuel sine wave generator, I would definitely give this one some serious consideration.
