The stand is great and long (longer than most you'd get at this price point), the mic holder is decent too. The springs are tight enough and on the top ones you can adjust the tension by shifting end points back and forth between pre-drilled holes.
However, the clamp is completely unusable.
Firstly, it is made out of parts that are welded together, rahter than being a solid stucture, like most of others.
Secondly, and most importantly, the plastic inlet is thick and is 1/3 the length of the tube that goes into it! As a result, no matter how hard you tighten it, the base of the boom is shifting around it, making whole thing feel wobbly.
Fortunately, the tube is a standard size, so I was able to use my previous leftover clamp form other arm, which made this thing usable and (frankly) great.
Even though this thing is worth its price, I'd recommend buying it only if you either have a spare table clamp, or with a separate clamp of your choise.
