I emailed them about something just a couple hours ago.
I lost the rubber button cover on my Battlelight, which I purchased used (like new, though) through a third party. I wanted to know if they had gotten around to making the new click on-off tailcap I had heard about, and if so, could I buy one (or the old type, if that's all they had).
I checked my email 30 minutes later and had a reply - they're sending me the new style tailcap, free.
I'd say I was surprised, but I've had the pleasure of doing business with Larue before. I'm definitely in the "if I want something and they make it, I'm buying it from them" camp.
BTW, that Battlelight is a great light for someone who wants something simple. No rings or mounts or cords to mess with, nothing to come loose; you take your light, and you stick it on your rail, and you're done. Also makes a good club.
