This replacement battery is stated to include a set of screwdrivers which are essential for the removal and replacement of the battery (in particular the three point and five point star-drivers). The screwdrivers were missing from the package rendering the replacement battery impossible to install

I'd searched for a replacement battery for a 2009 macbook pro and went for the extra cost of what looked like a quality product. It's been a few months now and it's working well - holds power for 4-6 hours. There are some very cheap alternatives out there but, to give an old mac a new lease of life - this has been worth the investment.

Works for my Macbook
