I have (1) P1D CE, (1) P1D (in "natural"), (2) L1D's, (2) L2D (one CE, one Q5). All working well. I gave one of the L1D's to my Manager several years ago. A couple of them sit on my workbenches. The only thing I don't like about them is that I don't think they support 14500's and I don't want to risk trying one in any of them.
These Fenix, were my first "real" flashlight purchasese other than about 15 maglight 2AA'a (in various flavors), a 3C maglight and an original gladius.
Sadly, I haven't really been excited enough about any of Fenix's offerings since then to purchase any of their later models.
