This works pretty nice (using with my Zoom F4 and have two extra XLR/TRS combo inputs). The only thing you should be aware of is the lack of phantom power and a fairly low output level. Otherwise very handy to have around, and works with both the handheld H5/H6 and with the F4 (also F8 I think, but not sure). Also it seems pretty big, heavy and perhaps a bit cumbersome depending on which body you put it on (kinda awkward on the F4)
