So yeah i love these stands. They are the perfect combination of heavy but not too heavy so i can still take them around with me without breaking my spine.
They go really high while still being really solid and stable. so are perfect for drum overheads, but they also go really low so when you run out of micro booms you can still mic up a Guitar cab or kick drum.
the telescoping boom arm is one of the main reasons i got these, just really convenient 1) for unscrewing mic clips and 2) for keeping out the way when you don't need such a long extension.
another reason i got these is because the wing nut to adjust the angle is a solid piece rather than some of the other ones which have the sliding T bar thing which rattles around.
also you can take the boom section off and just have it as a straight stand, so that means when I'm tracking vocals i can attach my se reflection filter straight on it rather than use the awful mounting system it comes with
I'm panning on getting another few of these stands just because there awesome and i never have to worry about them slipping/falling over/making noise, just set it and forget it and worry about more important things!
