1.) Due to power consumption (140mA) this microphone is fine for overnight use in field. Otherwise a powerful powerbank is needed.
2.) If you download (copy) recording data via network oder WLAN during recording there might be interruptions in the recordings because of the high sample rate
3.) Limited suitability for the construction of a batbox due to the design.
