These are perfect additions for your Macbook or iPad and as I have both of these then I needed to of them and they work perfect. They have all the adaptors you need concidering the very expensive iPad pro only has the C-USB adaptor these are excellent for the older USB products and SD Cards.
The first one I got worked pefect and made a big difference, especially as you can also charge your ipads with the adaptor attacthed. This is the reason why the adaptors are perfect for travel and make excellent addision to your kit.
You might not think you need them old products or electric items, but you will at some point untill they become totally obsolite. Until then these will do an excellent job of keeping them up to date and still useable.
