The reviewer found it best suited to owners of A1322/A1278 MacBook Pro models from 2009 through 2012 who want a straightforward swap and basic reliability; the single biggest reason to buy is the combination of a genuine-feeling 63.5Wh Li-Polymer pack with included screwdrivers that make installation easy.
