Use them all the time.
Several months ago on Good Morning America, they tested various products to see if they lived up to their claims. These balls were one of the items. I believe they gave them an a- for the grade. They also said they retailed for 20.00
A few months ago, I was in Ocean State Job Lot (one of those stores that have overstocks, etc.) and bought a pair for 2.99.
They really do work. They cut down dryer time, they reduce static cling, they fluff-up the towels well. The drawback is when you first start the dryer, and when the dryer is in its cool-down cycle, the balls revert to their hardness and they do make a bit of noise.
Geez ... I'm proud of myself ... after all this talk about "balls"; and especially "blue balls," I've not made one prurient comment ...
