This is a great quality product. My problem was that I though the middle element was not working properly (was not bright enough). After installing the new part, it turned out that this is normal that the middle spring is not as bright as the outer and the inner parts of the element. So I have basically wasted $200 by replacing a perfectly working part, and now have two working elements.
So don't worry if you experience the same "problem" - save your money in case you are not sure if the middle part of the triple element is not as bright.
