I agree with the others. My wife has had 3 and has refused the 4th. Her first (2003) didn't hold for 6 weeks. The second repaired the first, and the 3rd was on the other shoulder. Now the second needs repair and the docs don't thing it's a good idea. She says she KNOWS it's not a good idea. She can't lift a can of soup from the bottom shelf of the wall cabinet--she works around it.
It's not fun. I do have a lot of respect for athletes who are back playing in a year or less--don't know how the pitchers do it.
