Example Input: My husband and I purchased this as a Christmas present. It worked for about four days then broke. The screen will not turn on when it's plugged into the computer. We contacted Sony tech support who told us that it would cost $140 to get warranty work, because we had been outside of their 90-day free &#34;1 year manufacturing&#34; policy. I feel like I've gotten exactly what they promised - nothing. A complete waste of money. Do yourself a favor -- don't buy this.
Example Output: Bad review

Example Input: I bought it to my mom and she's been enjoying it. The battery last for couple of weeks, she has a very large area, but only 2 dogs so it's fine
Example Output: Good Review
