Title: Good Idea but...
Review: Exercises that extend rather than contract (squeeze) are great for tennis elbow and tendonitis in the forearm. I'm a guitar player and these exercises have given me priceless relief. When I saw this item I had to have it and it worked great for about 5 mins. Then the band snapped. This is cheap junk. Great idea. Poor materials. I was very disappointed. I've since been using a couple of size "64" rubber bands from Office Depot. A few mins every day does the trick.
