It is very suitable for a mini-disc. However, a small preamp did not hurt (to improve the level), and I think even a tube preamp would not be worse: in fact, this mic has a tendency to accentuate the treble (normal for a micro electret you say). Some lamps may give a little round ...
The mini-jack, if it is suitable for a small recorder, is quickly limited. To overcome this, I made a cable XLR 5 points to 2 XLR 3 points. A cable that is not in stock trading (this type of cable that is used for the Rode NT4 for example).
It comes with a good table leg, a clip with several adapters and we will not complain!
I use it for quite some time now
It is very reliable, solid.
Price / quality ratio right, even if Sony is not known for being tiny margins
In conclusion, a good mic properly. Not a killing, but it's very good.
