Works great in my Galaxy SIII, allows me to both take considerable more music and video with me, while also recording more pictures and video.I haven't done speed benchmarks on the card, but when copying mp3's to it at no point did I think &#34;this is a slow piece of crap.&#34;, as I have with other SD cards previously.  The included adapter made it work directly in my laptop as well.I do recommend anyone with a memory card this large does regular backups to their PC or other media - as nice as it is to be able to take 64gb of pictures, it would make it even worse if you lost your phone and they were the only copy.
