Pros: Very fast transfers (make sure you're plugged into a USB 2.0 port) and lots of space.

Cons: Power supply died on me a week out of the 30-day window for returns, and 12V/1500 mA power supplies are not cheap or easy to find.

Overall Review: Fantastic construction on the enclosure, shoddy construction on the cheap wall wart that comes with it.

Cons: The fans don't seem to move that much air.

Overall Review: One of the fans doesn't move when powered up. It starts spinning if I give it a boost and seems to stay on after that until the next time I unplug it, but this is not something that should happen on a brand new cooler.

Pros: Very fast when it's actually connected.

Cons: Drops link like it's hot.

Overall Review: Works great when it works, but the rest of the time I'm having to disable/re-enable it for it to stay connected to the AP for more than half a day. It's especially annoying when I have an M.2 adapter from the same brand bought at around the same time in a laptop 3 feet away, which has been rock-solid. I'd look elsewhere for external adapters.

Pros: Looks nice, has a ton of features if you get one that works.

Cons: Shoddy hardware.

Overall Review: DOA. Searching through various forums to find a fix reveals that this particular model dies with great frequency due to cheap components. I won't buy Saitek ever again.

Pros: It didn't set my house on fire

Cons: It could have set my house on fire

Overall Review: The first and only time I plugged this in and tried to fire up my new system, it sparked and threw smoke everywhere. I don't even know if the rest of my gear is damaged because I don't have a spare PSU until this fire hazard is RMA'd. If you want to burn your house down and die in horrible pain buy this PSU, otherwise try a different brand.

Pros: If you can make it work, it will give you two full-size firewire ports.

Cons: This card sucks. I had it for about a year, and in that time I was constantly messing with it to make my laptop recognize my external soundcard with it. Often the only way to get it working right was to plug everything in, then power cycle the sound card and reboot. Then go through the next round of headaches if I dared to suspend the laptop. Finally switched back to the laptop's internal FW port, and a simple power cycle of the soundcard got it running just fine, no screwing around with sound settings or rebooting required.

Overall Review: Other reviewers were right about the flimsy build quality. I tore the piece of junk apart with my bare hands. If you absolutely have to have an ExpressCard with FW ports, buy anything but this.
