I have not lost any lights, nor have I sold any of my 49 real performance lights, nor the six sub-performance lights that preceded them; I have them all except for two that I made gifts of. I have not broken any. No wife, kids or dog to borrow, break or chew my lights. I never set down a light when I am busy. It is in my hand or in its holster or clipped to my pocket, or on their home location, such as my flashlight tables or flashlight desk or in the safe. Twice, I had a light pop off of its pocket clip due to bumping into a door. I never loan out a real flashlight; I have some sub-junk lights for such purpose. I have a very active social life; many people marvel at the real performance lights that they see in action; some people have actually taken the initiative to actually purchase one after seeing them in action.
All this since October 2014, when I discovered real performance lights. I edc carry one or two lights every day. My biggest beat up light is TN36UT, and my smallest beat up light is S2 Baton. I have maintained only two lights new in box: MMU-X3 modded with 3 x XHP 50.2, and TM06S modded with 4 x 50.2.
