This is a one-seg tuner for the PSP. I used it about 10 times a few years ago after I bought it, but it has been stored at home since then. I no longer own a PSP, so I haven't been able to confirm its operation. The exterior is relatively clean, but it is a used item and has been stored for a long time. Please purchase only if you understand that it is being sold as-is and its operation has not been confirmed. Thank you for your understanding.
