I just got my battery in the mail today, 9/11/14, and I had trouble with battery slipping off the laptop. But as I tried to put it in again, it fitted very well!!! This is more affordable than buying from a battery store which is around $90. I would definitely recommend this battery. :)

Ex Output:
Positive Review

Ex Input:
Junk. It worked for a week, then stopped working. Looking at other reviews, it looks like quality of the units is inconsistent.

Negative Review
