SONY USB Jog Controller PCVA-JC1 This is a USB jog controller for SONY VAIO. I connected it to my PC and confirmed that it powered on. After the main PC broke down, I stored only the controller in its box. There is some slight discoloration on the surface of the unit due to use, but there are no noticeable scratches. Please judge the condition from the photos. Since I have not been able to confirm its operation, I cannot guarantee its operation or quality, so I will consider it a junk item. Please purchase with the understanding of this. Please understand that this is a used item. Please refrain from purchasing if you are looking for a perfect item or are overly concerned about details.
