This is an external harddisk bought by a poor lad on the streets of china for a very very low price. He used it to capture some video on this but he only found the last part of video everytime he shot. so he took his to the local repair shop. After riping the hard disk this is what they found. There is an 128 mb micro SD card inside a card reader which is connected to a usb converter. The card empties itself when it becomes full for making more space for more video.

This is another of such chinese goods.This is a wireless adapter. Usb wire is cut and placed into a box That's all it is. So,dont go for the cheap road side chinese goods probability is you can get one such products.
