Not reliable - SureFire XC1 Ultra-Compact LED Handgun Light

Ive carried (or tried to) this light for 2 yrs or so. Ive had nothing but problems. Tried to use it in some night training, but its so unreliable, I couldn't use it. The battery runs down in a few days, even without use. The rubber gasket that seals the battery came off after the first battery change. The cross switch is very easy to turn on during daylight hours, often without realizing it. If your life depends on carrying a light and gun, this is NOT the light for you. Streamlight TLR or Surefire X300 are much better options.
