Query: Destroys your clothes

I loved these things....at first. After several weeks of use, a lot of our bath towels and shirts started fraying around the edges. Before I tossed out the ruined items, I cut off the frayed bits and ran them through several cycles without the balls and guess what? No more fraying. These things will ruin your clothes. Not immediately, but they will tear at the fabric and one day you'll be pulling things out of the dryer and wonder why you bought these things. Great idea, but only for the sturdiest of materials... and then only if there are no weak or damaged areas.Do not bother buying.
