I just bought two of these for our two new Samsung Galaxy IV smart phones.  The adapters will make it possible for the card readers on our computers to accept these MicroSD cards if we find it worthwhile to pull them out of the phone case rather than use the USB &#34;dongle&#34; to move information on and off the phones, but.. most importantly, now I don't worry about storing audio books, favorite playlists, and video clips I might want to show someone on the phones.
