128GB in the size of a fingernail for this price, who'da thunk it?Works fine in my Sansa Clip Zip (using Rockbox software - probably fine with original firmware but I haven't tried it).NOTA BENE: As with all SDHC/XC cards, it comes from the factory formatted to ExFAT.For Rockbox at least, and probably other software, reformatting to FAT32 is required.If your device or software supports ExFAT, you won't care about this caveat.I'm only using it for MP3 bitrates, so I can't comment on speed issues.The dark red printing on the card is hard to read compared to the white on the 64GB cards.AWESOME!  Thank you Sandisk and Amazon.
