bought this 10500 generator less than a month ago and haven't used except for testing. The options for fuel was a selling point for me along with the doubling of the running watts of my old generator. Using propane instead of gasoline makes maintenance easier with easier storage. I can store propane in my shed for years so I always have on hand when power goes out unlike gas that last a year with sta-bil. Using propane won't gum up the carb as quickly as gas does and since i store the generator in my basement, no fumes venting from the gas cap when all gas is not used up. So far, so good.

Living in Houston with a 5 ton A/C unit, I needed a generator large enough to run it. Sure enough, once I installed a soft start on my Trane unit, this generator fires in up with no problem. Added a 50amp receptacle beside main panel and I'm now able to run entire house. And I'm running EXCLUSIVELY on natural gas; the lowest producing fuel. Very happy with purchase.

Really incredible unit overall. More than capable to power most homes and I swear this thing starts easier than most vehicles (remote start, push start, etc.). Multiple fuel sources are great and operated great with my testing. I would definitely recommend this unit to anyone.

Purchased this to be ready for hurricane season. Very pleased with the quality and it seems easy to handle and user friendly. The only thing we didn't realize is that we needed to hire an electrician to install a special outlet outside our home to allow the generator to run without using extension cords. We feel we made a smart purchase and did a lot of research before purchasing.

This will power the entire first floor of my house (4700 sq ft). All in it is only 20% of the cost of a fixed generator and we can take it with us when we move. I unpacked the generator, put oil in it and it started right up on first attempt. Great product.

Purchased this generator for the upcoming hurricane season and let me tell you, what a power house this bad boy is. I ran it just like the instructions said to follow and it power my entire house. I love the extra added feature of being a trifuel system. I am pretty sure i can power two small houses at the same time.

Really impressed with the quality of machine. I have only broken it in so far, but all seems excellent. Most impressive is debating about getting a tri-fuel when I don't have NG, but I might in the future. Instead of paying an extra 500 for a maybe, I settled on duo-fuel. Only to pick up and find I was upgraded for free. Wow Westinghouse! Thanks! My neighbor came over to help me get out of truck and he is in the process of ordering him one. Not looking for a Hurricane/power outage but can sleep knowing I'm covered for temporary power.

I bought this as an upgrade to my Wgen9500c, which is also a great generator. I wanted something with a better THD. According to the Westinghouse website, the THD for the 11500 watt unit is </= 5%. I didn't have equipment to verify the percentage, but when my AC unit and well pump start the generator doesn't surge like the 9500 watt unit. It also powers lights, refrigerators and other 120V items as well as stove, cooktop, water heaters and microwave with selective usage. I have only had this a short time, but my last Westinghouse unit was great. I feel confident that this unit will be great as well.

Works well but not as minimal hands on as I would've liked. Bought it so I could remote start the unit without having to go outside and switch on the power and turn on the gas supply- but if you leave everything in the remote start ready setting - the battery runs down in about three weeks - so I have to leave the trickle charger plugged in. I'm also running on the natural gas source but it doesn't like to start unless you put it on the LP gas switch setting. Overall, it's a solid product and it will do the job with some one off customizations.

I just bought this and glad I did. It has tri-fuel feature that I like. It comes assembled, all I had to add were 2 wheels and 2 support feet. Instructions and manual are detailed very well. It's easy to move around, rolling it in and out of the garage or storage building. The size is good for storage with plenty of power to run several electric devices at the same time. I definetely recommend this model if it meets your power needs.
