After a recent ice storm left us without power for 4 days, getting a generator seemed to be the next logical step, particularly since an even worse ice storm was predicted to arrive in the next few hours. I am not at all savvy when it comes to machines. I was extremely concerned that I would inadvertently screw something up while setting up the new generator under pressure. That did not occur because the instructions were absolutely clear and left no doubt at any point as to what the next step would be, and the only items I needed that didn't come in the box were a Phillips screwdriver and some gasoline. When I came to the end of the procedure and pressed the Start button, the generator started up immediately. As it turned out, the weather gurus were wrong about the second ice storm so I haven't had a chance to run the generator under actual emergency conditions . I know, though, that this machine will be ready when we need it because the maintenance and upkeep schedule that is included is very straightforward. The generator also comes with a data center that keeps track of hours of operation and that eliminates a lot of the guesswork.
The is my second WGen7500, recently moved to bigger home & needed second one. Had the first one for a couple of years and been very reliable during power outages.
