I like using dryer sheets because they can't be beat for preventing static cling. There are some loads, however, that I can't use dryer sheets in (towels, diapers, etc.) (Did you know that dryer sheets reduce the absorbency of such things as towels and diapers? I suppose less absorbent towels wouldn't be the end of the world, but woe to he who messes with the absorbency of my cloth diapers!)
So in such loads, I use tennis balls! They do everything that dryer balls are supposed to do, at 1/4 the price!
I know some people use dryer balls exclusively, but for those of us who prefer dryer sheets and don't want to spend close to $10 for a pair of dryer balls that we'll only use once in a while, tennis balls are a much less expensive alternative. (Just be sure to use clean ones!)
