I used this a while ago when migrating data from an HDD. I'm putting it up for sale since I don't have any use for it anymore. There is some dirt on the outer box, but there are no problems with the product itself. * The warranty period is one year from purchase, but it has already expired, so the warranty card is not included. ■ Product Specifications * Quoted from HP Length: 50cm LED indicator: Equipped with red/blue indicators, you can see the operating status at a glance.
