SPOTTED: Dryer Max Dryer Balls with Anti Static Technology

In my greener home living, the only complaint my husband has had is with the static cling that still exists despite using extra sheets of my Shaklee Fragrance Free Recyclable Dryer Sheets.  He much prefers his non-green dryer sheets, but I won’t budge.

My curiosity is definitely peaked after spotting these little gems. Dryer Max Dryer Balls with Anti Static Technology which says they use NO chemicals while naturally softening and fluffing and controls dryer static too!

Do they work?  Anyone try them?  The reviews around the web are varied.  Give me a greener leg please!
