Excerpt: I am using this with a SanDisk Clip+ 4gb Black. Easy installation, loaded songs from Win 7 Explorer no problem. No problems with read speed. After intitial loading the amount of "space" was 14.2gb I guess that's for default software on the card. I still would recommend this..
Summary: i got this sd for $10.98 afew mouths ago only down its14.81gb not 16gb as with all sd cards manufacturers smaller than advertising comes with a larger sd adapter for your computer most cellphones makers use SanDisk and no i don't work for SanDisk just believe in their quality so as for sd s buy SanDisk
