I bought this microphone to use on an acoustic violin, I've positioned him parallel to the strings just below the "G" String.
The installation was a simple process, the micro comes with a sticking compound and it's easy to use. the compound is not permanent, you can detach very easily.
The cable is a bit long since I'm using it with a wireless AKG receiver attached to the violin also.
The sound is just great, nice clear and tons of bass, I couldn't be more than happy.
It comes also with a nice little bag, unfortunately, I will not be using it since the micro is glued to the violin
