Feature:
the L and R outputs are not 2 separate outs, they are only left and right. Still, you can use them as separate outs by panning the tracks to only left or right. For example, I ran 2 microphones through the inputs, and had one mic's sound going to the left channel, and the other mic went to the right. Neither one went through the other side at all. Maybe that's a no brainer, but I thought I might try to help out a little.

Quality:
It would be nicer if it was metal because the plastic would be more likely to break, but it seems pretty sturdy and strong

Value:
Best pricing on a simple audio interface I've seen. Everyone else wants to overprice a simple in and out. This is a good deal.

Desirability:
sits on top of anything nicely. simple sleek design makes it look "high dollar." not too bulky, but could have a little more space between inputs. it's not bad, just if someone was using some huge cables, the might have to squeeze a little. if you're into all this smaller is better stuff though, and use slim cables like a normal person, you should be fine. It just doesn't waste any space

Sound:
Just got mine today. It's probably the cheapest USB interface available. Perfect, does exactly what it says. 4 inputs all together, but you can only use 2 at a time. The XLR and the front 1/4 input are both routed to the same channel as Line 1 input in the back. As for the outs, I most likely won't be using the RCA ports, but I'm sure some DJ's will appreciate it.

Ease of Use:
Very to use. Especially with an ASIO 4 All driver.

Support:
No service needed for me. Simple set up. Just follow the instruction on the setup.

Overall:
Someday I look forward to getting the Omega, but in all honesty, this is enough for me. I'm very proud of my Alpha, and I will keep it forever. No disappointments because I knew exactly what I was getting. And if anyone is disappointed, it's probably because they though they were getting more for some reason, or their having setup problems, and are blaming it on the box instead of their computer of software. Just get an ASIO driver and everything will work out fine!
