5 Stars Clip On Mike
Works great with the Nikon D300s but you must set the microphone volume to its lowest setting. Also if you clip it on your collar it tends to overload the camera input; just clip it around your shirt pocket and everthing is really good.
4 Stars works like it’s supposed to
sound quality isn’t great, but you can’t expect that at this price.
i like the long cable.

This product is compatible with all. It’s good.
best product at cheapest price that one can ever have
