Example Output: Negative

Example Input: I've bought several air beds from various manufacturers. I bought one identical to this one 1 1/2 years ago. It was comfortable but lost air after 3 months. I justified this as the user may have not taken care. However, I now believe its the brand. This one would not inflate at all. I will not buy this brand again. I've had great life from a better brands.
Example Output: Negative

Example Input: The description doesn't address the compatabilty issue with your computer. In my case, I purchased two, and had to return them both, since neither was recognized by my computer. Although the seller took them back for full credit, it's still a hassle, and a disappointment that it didn't do what was hoped it would. The rating doesn't necessarly rate the product, since it couldn't be rated because it was not compatable, it's more towards the lack of documentation regarding compatability.
Example Output:
Negative
