Dryer Max Dryer Balls Review

I purchased the dryer balls after some reviews online to see if they were worthwhile.  I decided that to be more effective, I probably needed two packages, as that is what most reviewers suggested.  I purchased the packages (4 balls total) and took them home with high hopes, but wary none the less.  I am happy to say that I have been using my dryer balls for almost 1 year, and have not purchased dryer sheets or fabric softener in that time.  I don't notice ANY difference in the softness of my towels or other clothes that would indicate that I didn't use any softener.  I love the fact that they are a green product and I can save money by not buying the softeners that I would normally use.  The one thing that I don't enjoy is the static buildup that comes from silkier fabrics and my microfiber cloths.  Other than that, I love them!
