Query: poor quality

This filter was not heavily used and was not abused and just fell apart on me one day when I was removing it from the lens. I had it only about a half of a year. The pictures did come out well with it, but for the cost and the amount of time it will work- just not worth it. Obviously, there are many people having the same problem.
