baseballboy may have more experiences of telling you about CI.
I am more comfortable with HAs and ASL.
My hub got a CI at late 30's and has seriously issues about finanical that he cant afford to buy another CI when his CI was lost. Insurance does not provide very well for adult people than children. My hub can afford hearing aids but his natural hearing level is destroyed by fixing it for CI. He is very upset about it. If CI stuff are affordable then my hub would continue to use CI. He said he will never go for another surgery agian. ONE surgery for CI is suffieicent for him.
