Came in, unpacked, had it running in under 15 minutes. Not a problem in that process. Only flaw I found was instructions say to connect the negative battery post to ground, but it turns out the positive battery post was also disconnected. Only flaw. I wired it myself, using an interlock for my square-D load center. Also bought a panel with two watt meters for the two power legs so that I could see what we were connecting. Easily runs two furnaces for heating, plenty of lights, and outlets for network, AT&T u-verse, 3 TVs and our side-by-side refrigerator freezer. And can also use 1 or 2 stove top elements if needed. Glad to say these 24 hour power outages will no longer cause us headaches. Highly recommend this thing, particularly when comparing prices vs functionality.
I looked at many generators and found this one to be the best value. I had to wait to get one but it was worth the wait. Powerful quiet and meets all the power needs for my home. Definitely a top choice.
WGen7500 was delivered 7 days early. Assembly took less then 30 minutes, attaching wheels, legs and filling the oil (even came with a funnel). It also came with a battery charger which is a nice bonus. All in all very satisfied.
