It has A very simple set up that is low-tech(disposable batteries & no wi-fi/Bluetooth connectivity) the has a feature to start/end recording with its audio input. Keeps your memory usage down as well as your clips cleaner.
I have an old mp3 that sputtered out on me and when I came across this little doozy I found it quite coinvent when the box said it had an mp3 feature It was a little hard to get the hang of but after reading the instructions it became quite easy :]
