Not being a CI user myself, I can't speak for myself. However, with the many years I've been on this board, I do see there is a big difference in results among CI users. You're totally right, what variables do exist play a big role, and I feel like I can say that because I see the same thing among HA users, of which I am. And, it's been interesting to see that two people who have very similar variables can have such different results. I think much of the argument is directed towards family members, or others who are hearing, that have higher expectations than are actually obtained. I see the point in that they (the family members or other hearies) don't actually experience what it sounds like through a CI, same as I haven't either. I think a good example here would be Angel, she was hearing all her life until the last few years, and she is now bi-laterally CI implanted. She was just commenting the other day that music is not what it used to sound like when she was hearing. And we see all too often on this board and elsewhere where people say "well, if you can hear, then it works perfect!" -- they don't understand that it still doesn't sound the same. What is the "norm" to one is not always the same to another, and some just don't get that.
