I've been very impressed with these mics so far.
The first week i tested it on everything, just to see how good they where; used it on drum oh, on congas, room mics, accoustic guitar, neck on double bass and even on vocals.
It worked supringsingly well on everything. I was especially surpirsed how good it sounded on vocals (I might even prefer it over a "traditional" large diaphragm condenser).
From what I've heard, in other studioes and from YouTube reviews, these are, in my oppinion, the most natural and accurate sounding small diaphragm condensers under 800 $
