I purchased this product when my original X-Box cable was worn out (but still working!) after almost ten years of continuous use. I hoped these keys would be reliable and they were. until they fail. The first key broke (no visible damage inside) after only a few weeks of use, the second after a year. I haven't played tournaments that didn't fail, but it would be a tragedy if they did. Agree to give these keys another try as they are pretty cheap but was let down by their durability.
