You may say its just a wire, but without it what's the point of having Mini DV? I needed it otherwise I wouldn't get to transfer any of my home movies onto PC. I had a Firewire card but no cable so I bought this and it works fine. It works with high data transfer compared to an ordinary USB wire which costs loads more for a mini DV cam upgrade. Infact I would have needed to pay 80 pounds for software so that I could save movies with a USB connector.
