Example Input: i dont think its working i saw nothing no changes while using this.maybe im expecting too much.ill give some more time then i'll try anything else. oh well live n learn.
Example Output: Bad review

Example Input: This camera was not very user-friendly at all. The first time I went to use it the shutter button got stuck. We could hear and see things flash on screen, but no picture. After spending almost a half hour trying everything, we finally gave up because this is too big of a headache for me. Now I'm just going to get a point-and-shoot type without all the complicated settings. My advice, do what everyone else does.
Example Output: Bad review

Example Input: The color is nice and matches my decor, but there was a split down the middle/end of it. I would not recommend this product. Not worth even the cheap price. It should have cost less. Very disappointed.
Example Output:
Bad review
