Bought this to work on Apple iPad with USB C connector. It is not recognised by the SanDisk iXpand app through the USB C connection so will not automatically back up photos. In looking at the manufacturer website, I found other disappointed customers so it is just an expensive USB stick. It can be used through the iPad files app where it recognised in 'locations'' as 'untitled' but not as 'iXpand'. It seems the USB C part only works with android devices - must have a lightning connection to work with Apple. Very disappointed.
