You're exactly right. I bought them once. Foolish me. All they do is make the clothes smell nice when they come out of the washer. However, by the time they come out of the dryer, that nice smell is gone.
Yeah, basically an expensive fragrance enhancer. I have used them and my clothes smell nice coming out of the washer and dryer. I guess it adds a fresher sent to my old workout clothes? I don't know. I can't say that I am going to buy them again. I've had the same bottle sitting around for over a year now.
Well, I like them. But then I never have much problem with static electricity in my clothes coming from the dryer. I think the crystals make the clothes smell nice, which is what I mainly use a fabric softner for!
