Product review (5 stars): just like hid bulbs
one of the things all the negative nellies on here need to realize, , you cannot, and i mean absolute cannot touch the element with your fingers. the oil on your hands is damaging to the element and will cause premature burnout,  if you touched it while installing it, your the reason it failed not the part. the oil casues a temperature difference in the metal and fatiques it causing a break in the element . just like hid bulbs, you cannot touch it . period.
