Query: Poor construction.

I bought this item. It worked for a few days. then broke. When i plugged it in, it would only work if i wiggled it, and held it in a certain place. I know its the cables problem, because i tried it with a few different items, and they all had the same problem. crap. pay a couple dollars more, for quality's sake.
