For the record, I've actually been dealing with a bad switch. I was documenting it over in SelfBuilt's review thread. I know, it should be documented here.
Long story short, my switch failed and I sent it to the
retailer who said they would perform any warranty work. They sort of fixed it, but it was buggy (details in the other thread) and I had to send it in to Klarus USA themselves. The darn light's been there in California for almost a month. I should note that Klarus has been pretty responsive to email though. It's just been slow. I haven't actually physically seen my Klarus XT11 since early May sometime.
And, uh, yeah, my tac ring actually
came broken, new out of the box. Weird. Anyway, they are replacing that too. And the clip. I think I won't add much more to that...seems you guys have it covered!
