Limited Range

Internal microphone noise quite strong.
Thus unusable for use without external Micro.

U-Rode VideoMic. Rode VideoMic Go little noise. Speak microphone preamp seems to be OK.

Not suitable for exteriors, since even when installing a Deadcat via the built-in microphones, wind noise on the plastic case is transferred.

Conclusion: Actually, as a mere recording device used (without internal mics). Perhaps interesting when it comes to little weight.
