Feature:
For this price, I think this unit is a pretty nice bang for the buck. 2 pre-amps, 8 analog in's, 2 S/PDIF in's, etc. The good thing is that it works as advertised. No problems.

Quality:
Seems pretty solid. Nicely built, good mobility because of its weight. I've put it in a laptop bag and flew on the plane with it. Works fine. The transformer included with mine works in all regions. I've used it in both Japan and Hong Kong without problems despite the different voltages in the 2 countries.

Value:
I considered the M-audio FW410 before purchasing this. But I've seen reviews where users were having problems with the drivers and such. So I looked into this unit. The price is reduced now and I think it's pretty good for an entry-level product. The firepod was not released yet when I made my purchase and that unit seems to be nice because of including 8 preamps (man!). So, if you have another 100 to spend, getting that might be even more bang for the buck.

Desirability:
Nice red, shiny color that pics on the net don't do justice to. ;)

Sound:
The included pre-amps work nicely. Low noise and enough gain for my purpose (recording pop vocals). I've only used it with my Studio Projects B1 and it's been serving me well.

Support:
Replied my email about a sample rate question within a week.

Overall:
The very one thing I was worried before purchasing an audio interface is to have to mess with my computer and IRQ's just to get the thing to work. This unit has been problem-less and easy to setup. Good and solid. I record it with SONAR on a PC laptop and it's been fine.
