Example Input: The reason why I gave it four stars in my rating was due to the fact that it took 3 weeks before all of these batteries were delivered. This happened several times and since this company does such a good job in shipping their products and packages from Amazon, I can understand how this could happen.
Example Output: Good Review

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: I bought this to use for my new iMac 15", which has a DVD drive (usb) but no card slot. When the product arrived, it was smaller than expected, about half of its size. However, after trying it in two drives from different manufacturers and several DVD-RW discs, I'm satisfied enough with it. It's not fast, nor is it quiet; It operates much more quietly (and less noisily) then my USB optical drive. If you just want something that's portable and cheap, try this.
Example Output:
Good Review
