It's really nicely made--that's not an issue at all. It's small, and not particularly light for its size--there's a good amount of metal there, and classy construction. It has a built in battery, and with a minidisc recorder with plugin power you can use it either with or without the battery--it doesn't seem to make any difference at all. But it's not made for phantom power--isn't low-z and doesn't have balanced connections--so if you're looking for something for that use,
the Pro24 is not the one. But you're not--for MD it's perfect.
It is relatively insensitive, which shouldn't be a problem for live recording of live concerts, and the noise level isn't particularly low, which, again shouldn't be a live concert problem. If you're thinking of using it for some sort of low-level ambient sound recording. . . . no, it won't do that. I see from your other posts that you're looking for a field recording mic? Nope--I don't think this is the one you want.
I do like the sound of it, relative to other things I have in the same price range (which would be a t-mic and the old and discontinued RadioShark stereo electrets--I won't even count the Griffin and Soundpro mics-in-a tube, which aren't worth buying, IMO)--warm, and relatively clean. But the insensitivity is, for me, the main problem. Sound Professionals has something they call a "SOUND PROFESSIONALS - POWERED STEREO MICROPHONE" for about $140 which might do for you, and the other possibility in their line is their SP-MICRO-1 ($99), which is extremely sensitive, or anything else in their line, of which there are widely varying sensitivity possibilities, all in the $50-100 range. I can't speak to the sound quality of any of those, though.
