Example Output: Negative Review

Example Input: seller must be informed by now that that this product is flawed. just doesn't care i guess. it's not properly shielded, so mice plugged into the USB port stutter and are pretty much unusable.
Example Output: Negative Review

Example Input: The board worked as advertised. This is my second board of this type. It has on board sound a video which is adequate for my purposes. Gamers may need a video card, but for routine gaming its fine.

Positive Review
