Example: I was very surprised at the high quality of the stitching, the sturdiness of the handles and the padding for my laptop. The price is amazingly low and the look is very good. I am quite happy with this purchase. It fit my MacBook Pro perfectly, with a little bit of room to spare.
Output: Positive Review

New input case for you: Update July 4, 2013:<br />I've been meaning to update, but hadn't gotten around to it until now. By February 2013, the battery held no charge and started to swell (just as the original had after 4 years of use.) Again, I would not buy this again knowing what I know now.<br /><br />Update for Dec 13, 2012: The battery turned out to be a piece of junk. It started to go downhill after 2 months, and now only holds a 15 minute charge with no warning that it is low. The computer just turns off. I would recommend against purchasing this battery, even at a cheap price.<br /><br />[previous review]<br />First of all, the finish doesn't match the actual MacBook, as the black MacBook is matte, and the battery is shiny. That's not a problem, since I have a leather cover for my computer. I \"trained\" the battery for over 2 weeks, completely emptying it each time, and it still doesn't keep very accurate time. Again I can make do, but it's something to be aware of. When it gets to about 20 minutes to go, you better either plug in or start saving everything that you don't want to lose.<br /><br />I read a few reviews where people are claiming 4 hours on a charge. I wasn't so lucky. On the lowest screen brightness setting, I can probably get about 2.5 hours out of one charge. I have had the battery for about a month now, so yeah, that's as good as it's ever going to be with this one. My original MacBook battery wasn't much better, so at least this one is cheap. If it dies on me anytime soon, as in stops holding a charge, I'll update this review. If you don't see anything below, my battery is still functioning the way it should.
Output:
Negative Review
