Bought this for the house in FL after Sandy. Luckily, we've never had to use it. Since the house was sold, this came back with me in the truck. The seal hasn't even been broken and obviously never been used. Don't need it since I have a bigger one here. I did have this same one here and it did the job it needed to. alternate running 2 fridges and a stand-up freezer. Says it runs 9 hours on 1/2 load but almost sure I remember getting more out of the one I had. Asking $200.
