Well, what can I say, this thing cannot hold a freaking SM58 without slowly, slowly bending down all the time. This is really frustrating, as I hoped to save some stage room with goosenecks on stage. What a pity.
You cannot trust it on the stage, as it adds one more layer of stress-thoughts: "will it bend down on my keyboard again? Will the microphone be at my mouth level when I sing the next line, while frantically trying to remember the lyrics?". Yeah, you get the idea.
Not 100% useless though - might find some use at.... damn, I have hard time coming up with a practical solution here. What is it even good for, if it doesn't hold the mic? I wonder if other brands are better?
