These directions were fantastically clear and made replacing my dud of a battery far less intimidating. I did have a moment of fleeting panic when I my do-do brain didn’t read explicit INSTALLATION instructions, just REMOVAL instructions, but of course common sense correctly dictated to reverse the steps. (Swoo!) Made all the easier by ordering the repair kit; saved hundreds of dollars and the hassle of going to an Apple store (in itself worth the 90 or so bucks!).
