What was my disappointment when I wanted to remove the battery in my MacBook Pro .... I unscrewed the frame (until the hopefully even if the driver already running, almost in vacuum) But then !!! when I tried to remove the screw from the battery to the Mac it was the drama. There is in this kit a multitude of tools but not the good. Need I remind you that the battery blocks access to many components and no tools to remove it we can not do much ..... PS: quality tools let whatever happens to be desired, after the price was not high either ...
