I recently purchased the WGen9500DF because I wanted a dual fuel generator to run on propane with a backup of gas. I used it for the first time yesterday for 5-1/2 hours while the power was out and it ran perfectly. I'm very happy with my purchase so far. I had a 50 AMP receptacle installed so I can connect a cable to the generator and have it connect to the whole house. No more extension cords!
I bought this generator over a month ago and used a couple times already. Very happy with it, easy to assemble out of the box and easy to understand features. Duel fuel is the way to go. Would recommend to anyone.
