Great product. Had bought it from PetCo originally, but they no longer carry it. So, I was very thrilled to find it online. It's exactly what we were looking for. A good sturdy tool that our Jack Russell puppy can handle easily.

Ex Output:
Good Review

Ex Input:
I was rather disappointed with this book that promised to offer a true account of the real life adventure of one courageous pilot in the Spanish Civil War. While written very well and quite interesting, it does seem at times like an essay which reads more like history than fiction. The author apparently decided after finishing the manuscript (which includes photographs from his personal collection) about half way through writing it, that he would create a story around it.

Ex Output:
Good Review

Ex Input:
It's OK but not great. The cover and binder is more than adequate for what it is. As you insert a CD or DVD, the top edge of the box slips off the binder, exposing the CDs or DVDs inside. Not worth it. I would NOT buy again. I'll go back to my original boxes: those can take abuse from everyday use and still work. This one can't.

Ex Output:
Bad review
