"Perfect"

Just the right size for my knitting and crafting patterns, lets me take them anywhere I go and helps when buying yarn and fabric because all the info I need is on my Nook.

"Works Great"

Works great in my Samsung Galaxy Note 2.Put the memory cards in and go to storage in the settings. Click format card and off you go.I have not measured read or write speed but i can tell you i can copy over 1Gb video file in just a few seconds.
