Hearing is my human right and you are enabling me to claim that privilege. I also want to recommend you to my friends as a worthy technician. Since you gave my hearing apparatus a tune up the squealing, shrieking and screeching in my ears has disappeared.
I am a happy customer and will speak to my contacts who never listen out of principle to join the club of people who in fact can hear, because with electronic adjustment, the message does arrive inside the brain. Although my hearing is electronically assisted my entire family is happy that I do not need enrol at the Goethe Institute where they teach lip reading. Thank you for a job well done.
