However good device with weaknesses

By and large satisfied with the device, but bothers me at the beginning and end of recording a "clack" to hear Bin is because you hear the sound of the button pressing (when recording with the built-in microphone).
But as I Rode with the SmartLav + use the recorder, I must also make no head me.
Many functions (Low Pass Filter, Noise Cut) I not use because I want to take the pure audio signal.
The built-in 2GB memory range for 23h in the highest quality.
The synchronization of the clock when you connect the PC did not work for me ...
I use the recorder for recording interviews using lavalier and is therefore perfectly adequate.
