Excerpt: I got a new iMac with Thunderbolt ports and I still need to use my external FireWire drives. This adapter does just what it's supposed to do. Just plug it in and everything works. No configuration needed.
Excerpt: I bought this product for use with an Apple iMac. I have several external Firewire devices (both firewire 400 and 800) and needed to be able to connect them to the computer via the thunderbolt port. I tried the adapter with an external hard drive, scanner, and DVD burner and all worked perfectly.
