I bought this to record a wide variety of voiceovers and musical instruments on battery power, but it has become my main audio interface for my Linux computer. It does everything that is advertised very well. I can record high-quality voice-overs on battery in a portable vocal booth. I can take it with me to record several instruments or mics out of a studio environment.
I think it really has no cons, with the slight exception of having only one USB port for both data and power, which I had to work around to use as my interface for Linux.
In short, if you are after a general and versatile recorder for voice, podcasts, instruments, small bands, etc, this has proven excellent for me.
