Ex Input:
These are by far the best quality and most durable dog toy I've found. I don't feel like they should be $25, but that's just me.

Ex Output:
Good Review


Ex Input:
The sound is horrible. You have these little 'headphones' that are supposed to go on over the ears and they don't even fit my 12 year old. He was so upset because it didn't work for them. No matter how tightly you put these on, his glasses pushed them off at every turn. They wouldn't stay put. Don't waste your money. I returned mine immediately. Bummed kids = big headache.

Ex Output:
Bad review


Ex Input:
I can't see how or why anyone could find this book to be funny, especially when it's packed with so many grammatical and vocabulary errors. On almost every page there's a run-on sentence which makes it difficult for the reader to understand what's being said. Even worse is the fact that a lot of them can (and do!) make absolutely no sense whatsoever.

Ex Output:

Bad review
