Query: Not worth the effort

I bought this product with high expectations to get my external CD-RW drive to record at faster speeds. This product, not only conflicted with my Windows XP performance until the release of the first XP service pack, but also doesnt work at all with my CD-RW drive. Ive tried everything, sending the product back, tech support (which wasnt that helpful), and using other products with it...and let me say that this product is in no way worth it. I have had no success with it and am unable to return it and am now forced to eat my loss and purchase another. Avoid my fate and by a different card.
