Query: Practically worthless

I should have taken the previous review more seriously. Total waste of $11. I'd return it if the cost of shipping wasn't more than its worth.I bought this thing for my kodak camera, the smallest adaptor was not small enough, despite specs seemed comparable.I thought I can at least use the other adaptor to charge my blackberry. It fits but as soon as I plug it into computer or the wall unit, it causes blackberry to reboot.Of the remaining two of the four, one is the common large one which comes all the time with accessories (I had four extra ones lying around). The last one is a just a coupler for joining two standard USB cables. Who in the damn world would even need that?The only useable piece in it maybe the retractable standard USB. Maybe even it doesn't work, since I did not really try it. I have tons of USB cables lying around, so I don't need yet another one. I needed the adaptors. Apparently this is not the product if you need adaptors.
