As someone that owns an iPad and a Note 3, this adapter is an easy way for me to carry both a lightning and a micro USB cord.
So long you use a half decent micro USB cord, iOS 8 has no problem with this adapter.
Click and collect seems to be there for most stores.
better off, buying the juiceup! power bank when DS sells them for $5, it comes with this adapter and you get a Powerbank for almost the same price.
