This is a mini DisplayPort to VGA adapter for connecting MacBooks and other devices to external monitors or projectors. The model number is Vodaview VV-MDPVGA-W-DO. This is a used item that I was using until recently, but I used it with the protective vinyl sheet still attached to the main body, so it should be in like-new condition if you peel it off. Also, a cap is included for the mini DisplayPort connector. The original plastic packaging is also included. Please consider this item, understanding that it is a used product. #mini_Display_Port_VGA_conversion
