It's a great solution for mobile recording, if you're into that kind of thing (though the BabyFace would be an even better option for two channel mobile recording).In short, this is a great product and I fully recommend it as long as its feature set meets your expectations.

The second is that the multipurpose knob on the front of the unit is somewhat of a pain to use, however I don't see a good alternate solution RME could have implemented
