Example Input: My husband and I didn't have time to attend an 8 hour birthing class at the hospital, so we opted for this video. It was very informative and helped us understand what was happening when we went to the hospital. It was a little cheesy, but definitely worth getting.
Example Output: Positive

Example Input: I ordered this DashMat for a specific vehicle, it was not the correct mat. I returned the original one and they sent me an exact duplicate of the wrong mat. I can't seem to get the correct one and therefore it sits in a box!!!!!!
Example Output: Negative

Example Input: I bought this on a whim, as it was the first Zen garden that I could find. I did not look at the reviews, and immediately regret it upon receiving my Zen garden. The other reviews summed it up nicely. The product is exactly what you pay for.Image:[...] - You can see the gap between the border/frame and the bottom piece. The tacks were put in, but did not hold the board to the border/frame. You should probably buy some wood glue, push lightly to separate the border, then press it back together with a small vice.
Example Output:
Negative
