Untwist Tool V2 is a tool that helps to untangle pairs of wires in CAT5e or CAT6 cable. It is very easy to use: you press the button, the head starts to rotate, you slowly feed the pair of wires and it is unraveled without any effort on your part. This tool not only untangles but also straightens, you can either press the wire against the hole of the head or use the special grooves on the side. On a single charge, the device can untangle about 2,400 pairs of wires, and when the battery is dead, a full charge will only take 45 minutes. A very compact and easy to use helper.
