Excellent product for converting from 6-pin connections found on most desktop computers and the 4-pin found on most laptop computers. I searched locally for a 4-pin to 4-pin cable to no avail. Most electronic stores I went into did not stock 4-pin/4-pin cables, only 4-pin/6-pin, so I ordered this unique adapter. I did think it was pricy for only one connector though. Originally, especially with the pic shown, it appears that you are getting two connectors which is what I anticipated. Wrong! There is only one adapter that comes with this item packaged. It works great though and can be used to connect your portable hard drive to a laptop especially if yours has the 4-pin connector like my Dell Inspirion 1526. Also, the 4-pin is essential for your connection of most Mini-DV Camcorders (4-pin) to your laptop computer which has 4-pin. Just insert cable into adapter, then the adapter into your laptop....and your in business ! The price isn't bad when you consider the alternative though...It Works !
