Although good quality product, it doesn't fit my ear at all. None of the sizes fit comfortably or snug. I can't use it at all and just wasted my money.

Ex Output:
Negative


Ex Input:
If you believe people have an eternal soul, this book is not for you. If you believe death is the end physically and spiritually, and you want your child to believe that, maybe you will like this book. I found it not comforting at all, and not what I want my child to believe.

Ex Output:
Negative
