Pros: I bought one of these made by Syba from Newegg and it worked PERFECTLY, but I LOST it.

Cons: When I ordered a replacement, the one I received was by I/O crest. I assumed it was the same, so I opened it and foolishly threw away the packaging. It didn't work at all. The LED never even lit up. The card itself doesn't lock into the slot. And I can't return it. If you order one of these, keep the packaging so you can return it if faulty.
