Query: This is more like a $100 fan than a swamp cooler.

It isn't very effective. You have to put over 10#'s of ice in it just to feel a few degrees cooler than a regular fan and as soon as the ice melts it is just a fan and not a swamp cooler at all. It isn't really worth the money I paid for it and I am very disappointed.
