Complete failure - SureFire XC1 Ultra-Compact LED Handgun Light

After 400 rounds at the range and less than a month carry the light has failed. I own over ten surefire products and have always paid the premium for a guarantee that light will be there when I need it. All my Surefire products from Filament bulbs to LEDs have always worked and never failed no matter how much I beat them up in the field, work, or at home. I am very disappointed with this product. The wide consistent light pattern, size, and AAA is great. However, the constant on switch needs tactile feedback and the momentary switches could be a little longer. I could have lived with the minor issues but this failure put absolute doubt into trusting this light with my life need the situation arise.
