We used this for my sons Astro a40 headset. The lock levers on this one are very loose, the roller and its supporting housing is made from very cheap plastic, the shifting cable was not install properly so it can shift from 1-4 positions only. Good for the price and comes with all the hardware. She doesnt know this yet. Ugh. I am slightly disappointed that the print is so faded; was hoping for something more vibrant and the material is on the thin side. They are fragile but most jewelry is so just be careful handling them-none of mine have rusted or broken yet and if they do I?d probably buy more I like them that much. You also may have left the screws too loose if it seemed wobbly or unstable. I was hoping to have similar performance, but these things just werent for me. First, Im so SO.
