For the price, this mic is very good value. There is a slight hiss when using it, so for high-quality recording, it's not the best option. But to just over 11 quid... it works much better than I expected. I plugged the receiver straight into a Marshall amp.
It could be used (with a jack plug-3.5mm adaptor) in a camcorder with external mic socket. Not sure about the quality, but for long shots with speech it's better than nothing? It transmits clearly up to 30m. The mic picks up everything clearly and it transmits well. It's ideal for public speaking indoors or outside.
As mentioned the only down side is the background hiss. Turn up the bass and turn down the treble and it improves somewhat. A DI box or something may help. Just bear that in mind.
Anyway for the price, it's good.
