Works great with Sony PRS e-readers with Sony Memory Stick Duo expansion slot PRS-505 and up. The PRS-505 had slots for a Memory Stick Duo and a full-size SD card, but according to the manual could take a larger Sony card up to 8GB, while the maximum SD card slot is 2GB. As far as I know, later Sony readers up to the T series could process memory expansion cards up to 32 GB in both expansion slots. Proven in Sony PRS-505, PRS-600, PRS-650, PRS-900 and PRS-950. This adapter and a Micro SDHC card up to 32GB will work great on all but the PRS-505. To my knowledge, older Sony e-readers are not compatible with SDXC cards and the PRS-300 and PRS-350 do not have expandable memory.
