Craig, you are correct, the BATONLITE is much larger than the SOLITAIRE, more on the order of a typical kubaton after which it is likely modeled. I own a BATONLITE and use it as edc with my keys and sometimes the tiny Leatherman Micra attached. While I have my doubts about the screeners at one's point of departure giving it a pass (I have always just checked it through within other luggage) it seems to pass casual security with PHRASECENSOREDPOSTERSHOULDKNOWBETTER. who notice it and only rarely wonder aloud what is that "thing" on your keys(?). My straight-faced answer always is that it is my flashlight I use to chivalrously illuminate the way for my wife whenever needed. The unit is very well constructed. I have carelessly dropped it numerous times without serious penalty. Slight damage has ocurred on the edge of the lens portion, but IIRC, it is constructed of very tough Lexan and any damage could be viewed as merely patina.
