Really sorry to hear that rhd ...My #200 arrived two days ago. I've been using it sporadically, maybe 5 minutes of use in total since then.
Then this evening I got it out again, turned it on, and about 3 seconds later it went dark. I can now see that there's a pinkish light (presumably the IR diode), but no green.
Not sure what's going on here, but I'm not impressed - not for $115.
I'm thinking that if the IR diode is still firing, then maybe it's some sort of crystal alignment issue? I haven't disassembled anything to investigate further - didn't want to invalidate any warranty - though the fact that I took off all the stickers may have accomplished this anyway.
Honestly - pretty crappy lifespan for a 532nm I spent $115 on. I know it's no $700 CNI product, but 5 minutes of use over 2 days? Booo.
