The mic arm is very good value for money, does what it is supposed to. Finding the right amount of tightening for the joints can be a bit fiddly, but once you have it set, you can forget about it.
The only negative aspect is that the arm feels a bit flimsy, I was scared I would break something setting it to the right position. Although apparently the arm can take it. Overall pretty happy with the product, very good value for money.
