Im honestly not being sarcastic or trying to threadcrap. But I must be missing something. $10 for a 6 inch long 100 lumen light? Compared to the let's say Meritline's one AA (or one 14500 cell) light which is shorter and puts out 150-200 lumen and costs between $6 and $10 depending on sales. Why does this light keep popping up as a great deal?
