Very easy instructions. Thank you. My only snag was that the ten screws holding the battery were extremely reluctant to undo. wrecked the IFxit screw driver. Fortunately, I had another one. My tip for anyone doing this little job, is to use quit a lot of downward pressure on the screws. Turn them 1/4 turn anticlockwise and back again. Do this several times until they turn freely. You will then have an easy job. I will replace those screws with a tiny blob of 'Never Seize'.
