Example Input: When i plugged in on first time, sparks appeared from it, as soon after connecting, some electric shocks came out. The charger seems ok but obviously this is not designed for Lenovo Vostro 1520.
Example Output: Bad review

Example Input: What a disappointment. My mom bought this for me as soon as it came out in theaters over Thanksgiving. As I watched the movie my first question was "What's with all the screaming and cussing?" After seeing it, I could not believe what the kids were doing on that island. That being said, after watching the entire movie, there is no redeeming quality. The film drags until you just want to jump through your TV screen because of how annoying everything is. It's an insult to real Native Americans.
Example Output: Bad review

Example Input: It doesn't really work well. The cover is very hard to remove. I had a problem with it sticking on the iPad because when trying to remove the first time and there was some kind of grease or dust that made bubbles. Second time, after placing case on, still have this problem. Not happy about it, would not recommend it. In addition, my ipad slips out easily. There are two pieces where the magnets are, one magnetic closure for cover, other holds cover.
Example Output:
Bad review
