After reading the pair of "doesn't work" reviews from the same person, I decided to try it anyway, figuring that Amazon would do an easy refund if it really didn't work (also, I've had good experiences with other Sonnet products in the past).It works just fine for me. I've used it to connect an iPod and an iSight to the Firewire800 port on my Powerbook, both work fine. It seems a decent value and I'm happy with it.
