Q: I was very excited to be able to get a adapter these size for the price. The only down side is that after a couple of days it stop working, I tried a troubleshoot it by using different computers still did not work. I guess that the adapter must of just burned out or something. I try and prevent that by putting it in a well ventilated area. When I bought this I thought to myself i would not be the few people that had a problem, but I did. All I would have to say is buy at your own risk.
