Example Input: Excellent product, easy to read without glasses, works on every type of battery and does not require any additional power source other than batteries. I use it with a small LED flashlight for all kinds of things including checking my golf swing. The LED is much stronger then the old flashlight. A plus is that I can clip this device anywhere in place which makes clipping or removing your shoes even easier. If you need a great reliable wireless device, get this.
Example Output: Good Review

Example Input: My son loves these. He only doesn't play with them so they don't last very long but we find that it helps to break them down and put it away a few days before bedtime as the first thing he does is bite on these things :)
Example Output: Good Review

Example Input: I've been an avid fan of the John Rain series ever since I first read the introduction in 1984. Since then they have become a mainstay of genre novels from my favorite author to one that might be considered better than all but one. The story was weak at best.. The characters were dull and predictable and had minimal depth. And though it took us back through time, we didn't really get close enough for me with just a single character to "feel" their emotions.
Example Output:
Bad review
