This interface has worked well for me for some years now. When using the guitar (input 2) and a microphone, occasionally strange electronic interference occurs. I've never noticed any latency. I like having the knobs to quickly dial in levels etc. Very easy to work with unit.
Well, it's pretty good, since my PC's internal audio card is sucks, so i went myself and get this beast from my uncle who worked as an Audio Engineer, yeah, it's so good when now i can do stuffs that i want without stupid audio latency buffer limitation, it's a full direct access to everything lol.
