I bought this to hold my SM-57 I use for vocals in our band and it does that job fine. My SM-57 mic clip screws on perfectly.
It's easy to use, folds up neatly and has a nifty little clip to keep the cable tidy. Yes, it's plastic but I've seen much worse plastic than this. My cats managed to topple it twice onto a hard, tiled floor, but both times it came out completely unscathed.
If a somebody falls onto it then no, I imagine it wouldn't take a beating like a heavy duty metal one, but at this price why should it?
I gave it 4 stars all round because it's outstanding value for money!
Bear in mind that the screw knobs might not take a severe tightening, but then again, there is no need to, since it holds without such punishment. This is my only point of concern and I'm going to be kind to my knobs since they are clearly not 'heavy duty'.
I would recommend this stand to anyone who hasn't got a small fortune to spend on one. It's hard to imagine anything better for the money. 'For the money' it would be 5 stars, but in the real world you need perspective!
