I got email message from my friend about asking what is best model of CI? I dunno... He wants to know what model of CI does your friend have? AB, Cochlear and BEA before he will got new CI. If you have a friend, does this person born with profound deafness and hear better after CI? Is this person hates deaf with ASL? Is this person both hearing and ASL? Other? I will reply him so he can get survey samples models of CI who experiencing them.
