My L2P has two issues. First, the rubber protrudes a bit too far to stand on end, as it is supposed to be able to. How did you fix this, Tigerhawk?
Second, my L2P does not like vibration. Specifically, the tailcap-to-body contact. After each day of carrying my L2P in a reasonably padded bag on my motorcycle, the light would be dim or flicker until I loosened and retightened the tailcap. I made sure the contact surfaces were polished finely. I have never had this problem with the L2P at any time other than taking it on motorcycle trips.
To deviate from the question, since nobody asked, I would not buy another Fenix. I think they are a little overpriced for what you get. Although my E1 works fine enough, and the threads are butter-smooth, the beam is unnecessarily ringy. Also, the P1 I received was DOA. It would flicker and never put out anywhere near it's full output, which was confirmed by the retailer. The metal casing of the P1 was so embarrassingly thin it felt downright cheap, and when the flashlight was "off," there was no spring to keep the battery from banging back and forth into the positive contact. Considering the stage in the LED flashlight's evolution, and considering where the Fenix are made, and the quality issues I have seen so far, I can get the same for less elsewhere nowadays. I really tire of some sellers asking made-in-USA prices for made-in-China flashlights.
That's just my take.
