This PNY SD card was used in my ipod mini DIIY mod. I thought it would work in an OTG adaptor with the X3 second generation. So I swapped a 128gb card into the mini (for sale separately), and removed this card.
Long story short, the card was great in the ipod mini but did not work in the FIIO OTG scenario. I am lazy and do no want to put this back into the mini.
Includes the PNY plastic protective case. Works fine; currently formatted ExFAT.
