Example Input: I'm not sure where to go wrong with this review. The first time I put it on my Nexus 7. It is too small, but the second time, it stretched out enough that you could tell its there. When you stretch the thing, it loses contact and stops working. Not worth trying again. Went back to Zagg, who also made an excellent product. This one just does a bad job. Save your money!
Example Output: Bad review

Example Input: Was nice enough to carry the food with out a mess but it gets too difficult and annoying for my cats while it's on their nose - they just lay down instead of trying get up to go. Maybe if I put something inside as an "aid" then they'd like it. They are in fact able to reach the top which is why she did so well when using this product. Good quality though overall for how sturdy it is.
Example Output:
Good Review
