Example Input: 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.
Example Output: Negative

Example Input: This book came out a long time ago. I read it when it first came out and it introduced me into the world of ghosts and and lore. I was 12 years old then in 1982 and even now when I pick it up to read....it still takes me back to the feeling...when I first picked it up and sent shivers down my spine...in a fun way of course. The stories and the drawings were perfect together. A great book. I have all 3 volumes now and I hope he comes out with a 4th one soon.Thanks Alvin and Stephen for scaring the pants off of me when I was 12.
Example Output: Positive
