I can use this device with multiple microphones to either record in mono for each channel or combine them into stereo inputs. The Zoom is compact, relatively easy to use and sounds great! I would recommend to use external microphones, as the built in ones are mediocre. They are not un-useable, good enough for voice, but for field recordings, it's better to grab yourself 1 or 2 Shure SM58's or an equal quality mic.
