Nice product, very rapid delivery.
I use this Rode mike on a Canon HV20 whenever the situation needs better sound control.
Often I can film without this external mike, and then enjoy the small size and mobility of the bare HV20. However, the internal mike cannot cope if the wind is blowing. Also the internal mike points skywards and picks up planes that my ears do not notice. Also the Canon's internal mike seems to distort base sounds.
In any of these cases I screw the Rode mike onto the HV20, and plug little earphones into my ears to monitor the sound. It makes the HV20 more cumbersome to handle but this inconvenience is nothing compared with the better control over sound recording.
