Lever would not tighten properly right out of the box. After setting up my arm as best as I could, I attempted to set up a USB sound card with a microphone. Then I heard a loud buzz and then was shocked by the microphone. I removed it quickly. Upon closer inspection, it smelled of burning. The inside of the sound card was also cracked and loose. It is very disappointing and of very poor quality. I do not recommend anyone to buy this product.
