Terrible for professional requirements

Also, when I bought this microphone for professional purposes, I'm not Tonspezialist. I'm completely out of my ear and my personal claim. Primarily I felt attracted by the good reviews and of course the low price and was hoping to get a good product for less money.

Wanted I have a microphone for video interviews in which I purpose extension cord directly into the camera (Canon 5D III) connect the microphone or in a digital recorder (Zoom H2N).

The recordings with the Canon were quite sobering. In general the sound is by feeding an external microphone at the Canon anyway not particularly impressive. Even with brand microphones Rode. But the microphone of Ultra Disk is on the quality remains well below. Only post I can make up for the dull sound and the noise reasonably again.
Somewhat better the result was recording device with the Zoom H2N. But again: not really clean and clear and pretty dull despite trying out various settings.

For the price and with a little reworking the sound quality quite useful microphone. However, if you need an excellent and clear sound, ought to grab a little deeper into their pockets.

I answer questions like my comment.
