Query: Worst product and worst service

I live in Arizona and knew that the product was an evaporative cooler. When I received it it worked ok but the pump died after a month. So I have just a fan no cooler. I went to Sunpentown and they said they would send another unit. After 2 weeks I called and told them I had not receive a replacement. "Oh Sorry!" they said and then shipped my replacement a week later. This one lasted 10 days before the pump went out. I tried Sunpentown again and they told me that they were busy but would get right back to me. Not a chance that that is going to happen. And it hasn't. All you end up with for your money is a very expensive floor fan that isn't even very good for that. Please save your money. This product is worthless
