Query: Fall apart after multiple uses

The set I have just fell apart after about one month of "normal" use. This was my second set. The first set fell apart after one week of use and returned and exchanged them, thinking they were defective. I'm not spending more money on another set and don't want the hassle of exchanging them only to have the next set disintegrate. I like the idea of chemical and perfume free dryer softening, but I'm going to try tennis balls next, and if that doesn't work, I'll go back to dryer sheets. Save you money and don't purchase this item.
