I can't believe no one has written a review for SSI!! Shame on us! I had therapy there following carpal tunnel syndrome a couple of years ago. They are excellent!!. My therapist felt I needed additional tools to work with to enhance my range of motion and build up strength in my hand. No problem; the next time I came in for therapy, the tools I needed were there. These people are WONDERFUL to say the least. My husband has used them also, following rotator cuff surgery. Outstanding!!
