Better than nothing
My 2010 MacBook Pro's battery was swelling rather badly, and I needed to replace it before it burst my computer at the seams. Installation was easy enough, but I used other tools as the ones they included were not very good (the metal on these was too soft to turn any of the screws). The battery charges and works, but doesn't hold a charge very long. It's half as effective as the swelled battery I replaced, but since I mostly use my laptop while connected to power, I left it in. If anything changes regarding its performance I will update this review.
