If you need information with regard to your iPad Air 2 then this is the one manual for you. If there is a problem it be solved by referencing this manual. I can’t think of anything that is not covered. Just great!
One small detail though, the printed font could be a little bigger for those of advanced years whose ability to see is rather on the wain.
Just right for what I need, the only problem is that because it has been put on to A5 size paper, the printing is a bit small, which I suppose wouldn't happen if it was on A4, other than that, it's ok
