Review on FISTERS Solar Powered Attic Foldable by David Tadder

The "battery" he refers to in the product description is only for the solar fan, to provide "stable power" for the fan, which is called a charge controller in solar systems, not as a battery. Don't buy this "slightly" overpriced fan if you need to run the fan at night. If you're going to hang this on the stairs get a couple more hands, the solar panel has a hinge in the middle and there's no way to lock it in the open position, and don't connect the fan to the 'battery' ". mine came and i managed to lose some numbers, one side has no fan guard, it's completely open.
