    Ease of setup  /  Good accompanying software  /  Good value for money  /  Lightweight  / 

    Overall, the audiomoth is a great tool. It’s an affordable unit that does well in a variety of situations. The apps used to make recording schedules and set up the unit are straightforward and have a nice interface. One downside is that the clock resets every time the batteries come out.
