Got an L7 for christmas and have had 0 issues with it. Very simple switching, twist the bezel for constant on and press tail button for momentary. There is no tailcap on this light, the tail button just pushes the battery forward so it makes contact with the bezel.
I think part of the reason it's not mentioned much on cpf (I've seen maybe 6 posts about it in the past 2 or so years) is it's too large for most people here to pocket carry. 8 inches long and just under 1.5 inches wide at the bezel end. I carried it fine for about 2 months in my front jeans pocket until I noticed that the extra aggressive knurling was chewing up my pocket. The knurling is much rougher then on my other Surefires (6P, Z3, E2E).
The beam is great, good combination of strong spill light and decent throw. The P60 lamp assembly will outhrow the L7 by a bit but loses out on overal output.
Another reason it's not talked about much is the NICD batteries, most people seem to want LI-IONs nowadays. But there's really nothing wrong with NICDs. I get around an hour or so of regulated light, then a short period where it's hard to tell if it's still in regulation or not, then it usually flickers and drops down to an even lower level for how long I don't know as I usually switch out batteries about now, even though it's still spitting out 20 or so lumens.
