I use the recorder primarily on video recording to sufficiently have sound material for post available. Although I use a high quality external microphone to my camcorder, the zoom-material can be heard better. To hear that I have almost always rework the material and adjust down to have no great leaps in quality in the finished video.
Minus: Abundant idiotic menu navigation, many settings can not be changed during recording, high energy consumption. The wuschig Soft Keyboard is absolutely no feedback. The plastic casing cracks and creaks with every movement - and all lands on the recording.
