Good for physical therapy.
I bought this thing to work cramps and stiffness out of my back.  For that purpose it works great.  Durable, hard, and useful.  The only draw back is the stink of &#34;facon&#34; (that fake bacon smell), because it is made of unvulcanized rubber.  No idea what-so-ever about its efficacy as a lacrosse ball.
