Example Input: I only used it a couple of times, a tiny bit of water leaked into the battery compartment and now it is rusted and won't turn on.
Example Output: Negative

Example Input: I purchased this airbed because I wanted to sleep in the same room as my newborn. Yes, I'm one of those paranoid new moms. This bed goes above and beyond. I wanted to buy the AeroBed first because I'm one of those people who hates to buy cheaper items because they usually break or whatever. I'm pretty much a sucker for the theory that expensive = quality. However, I went with my gut and decided to try this airbed having never heard of the company before. Listen to your gut! It inflates in 3 minutes and deflates in about 3 minutes. If you want it to be more firm & allow the air to settle in better, you should leave it in there for about 7-10min. Not a big deal at all. Go do something in another room while you're inflating it. This thing can also handle a lot of weight. When I'm sleeping on the airbed, my husband comes in the room to tell me he wants to sleep in this bed too because it's so comfy. Great Buy!
Example Output: Positive

Example Input: A decent story that gets you to turn the pages. The problem is, there aren't enough pages. The story just ends leaving you in the middle of an action sequence. I don't like paying $8 for a book that leaves you forced to buy the next one in a series. I don't mind series (thought I'm not that much into them), but each book in a series should stand alone.
Example Output:
Negative
