Query: Portable Air Cooler

As a fan it works well, however as a cooler, it doesn't cool much, unless you have a ton of Ice. I don't recommend this product. I returned the first one thinking that it was damaged, I sent it back, and they sent me another, and it didn't cool either. So I sent that one back too. Now I'm waiting to be refunded.
