I think it's a keeper.  It sounds remarkably good in the car with pretty good rejection of the road noise.  Battery life rocks, still on original charge with 2hours of messing around ( they claim 4 without phantom power)

I still hate the UI, too easy to get lost in a loop where you want to make a setting that should be non destructive to the recording yet you manage to hit the pause / stop anyway.. ( user error sure,  but no help  from the H4 in avoiding it)
