I do for youtube videos and movies in HD with a Nikon D5100. Since there built Micro unfortunately the loud sound of the autofocus takes had to be an external Micro. In 10 class I want me not at first look ... So seen, read reviews and then they ordered here for 32, which are, after all, round 65DM, not just a little. The processing is orderly, that is bad solved, because you have to withdraw a compression spring with a small screwdriver, so that you can insert with button cell insert the small button cell. This could have been a better solution. The promised features: "Three switchable polar patterns: omni, cardioid, figure eight" has not the microphone, but only a slide switch, with which you can turn on the micro or the gain by the button cell. After a few test shots I give the microphone to an average good score when it comes to the sound. DS can not compete as a small microphone capsule with a studio microphone is clear, but somehow the sound is a little dull, as usual, but still acceptable. On the whole, I am quite satisfied, although I would have Given the price expected a bit more qualitative sound.
