I use it in my Sansa Clip Zip 8GB MP3 player and now I have 40GB for music.The included adapter allows me to remove the card from my player and add and subtract music using a standard card reader on my computer without having to plug in my MP3 player.When I'm done I slip the micro card back into the player, let the MP3 player refresh itself, and I'm good to go.This card is a class 10 unit so it's also good for expansion ports on Video cameras as well.-v-
