Disappointed...
I was looking for a "firm" stress ball and this item stated that it is firm.  I just received it a moment ago and can emphatically say that it is not firm.  It is between a light/medium density and exertion pressure.  I am so disappointed.  Now I will have to keep looking, but it won't be online.  I'd rather a brick and mortar so that I can touch and feel.  Based on what I received, I would not purchase this again nor would I recommend it.
