The generator seems like a fine product. The main issues I have had have been out-of-date (apparently) documentation. The user manual, in the section about transporting the unit, refers to controls which are not on the console. The user manual also states the wrong part numbers for the gas and propane high-altitude kits. We're at 5500 feet, so the high altitude jets are required to be installed for the warranty. I found the correct ones (I assume) on the Westinghouse parts website. (I sent some questions to Westinghouse trying to confirm this but never received a reply to this day, even after pinging them again.) The only documentation for installing a propane high-altitude kit that I could find was for an open-frame generator, but it was fairly straightforward to adapt for this one. The blog (and pdf) that documents how to do install the high-altitude kit for gas is unclear from the photos on how to disconnect the wiring for the carburetor in order to remove it - there is one wire that goes from a box on top of the carburetor, over the top of things and through a metal twist that holds some wiring together, and down the right side into the bottom, with no connection plug in sight or that can be felt, but it is too taut to remove the carburetor as-is. I finally was able to remove the carburetor without disconnecting this wire, by releasing the twist, which gave me some slack to slide the carburetor off the posts and feed it through to the front of the unit to continue the jet replacement process. (I took copious, high-res photos throughout this process to use as my own reference, so Westinghouse, if you want them to update your documentation, contact me.) I'm not a mechanic but I was able to do this in about 6 hours.
After completing the jets replacements, I filled it with oil and put in some gas. It is very difficult to see whether the oil is full or not - it has a completely horizontal opening, which drips oil if you get too much in, but is pretty hard (impossible, actually) to tell that it is getting to that point. The supplied funnel actually screws into this horizontal hole for filling. The instructions say to pour the entire provided bottle of oil into the generator, but also says not to overfill. Well, it was overfull, and I went through several paper towels trying to catch all the runoff. It would be better if the opening for adding/checking oil was at a bit of an upward angle, and straight towards the outside, so you could look in (say, down through the funnel?)
I then tested it in eco-mode with a hair dryer on two settings, with gas and propane, using the remote control and then the push button, and that worked correctly. Finally I tried to use the pull-cord. It backfired on my first attempt and then I was unable to get it to start. This may be because the engine is too big for me to get it to turn over (I am a 59-year old female, fairly fit but maybe not strong enough.) It still started ok afterwards with the remote.
As far as loudness goes, some say it is very quiet. I do not have other generators to compare this to. I walked around to the front of my house while it was running and I definitely could still hear it - it sounded like a distant lawnmower running.
I'll have to say, this generator may come in handy some day, but I hope it doesn't!
