Cochlear implants

Hello, my name is Chelsea and I am 17 years old. I am writing a report in school on cochlear implants and I was wondering if anyone who currently (or even previously) used these implants could answer a few questions. Personal details such as you age, name or gender are not required when answering these questions.

1. On a scale of 1-10, how much has your cochlear implant improved your hearing?

2. Have your implants ever malfunctioned or stopped working? If yes, do you know why?

3. Did you find it was an easy process to get your implant?

4. Roughly how long did it take from the time you wanted the implant to the time you were actually given the implant?

Thank you very much for taking time to read this. Any information and/or opinions you have to offer will be very valuable!
