I have read many reviews on generators this size (WGen9500DF). I'm very happy with this dual fuel unit, I like the propane feature, you don't have to worry about gasoline getting stale. The price was in line with inferior brands.
I like it a lot, it was easy to put together, nice and heavy, but I have yet to use it, it’s been only one day since I put it together and got the gasoline and propane for it.
I spent a year researching and finally came up with the WGen9500DFc and I don't think I will have any regrets. It took me all of 25 minutes to unload and set up. I did not fire it up immediately as it was nightfall and due to consideration for my neighbors. Bright and early the next day, I powered the device on, pressed the remote... waited for the predictable initial 'coughs', then voila.. the beast powered on. I can hardly wait for the next hurricane and power outage
