Surefire Z61 reliability?

[N/Apower]

I know SF clicky's are not very reliable, but is the Z61 good/bad/mediocre? How does it compare to the Z68 and the Z57?

How is this compared? Also, is it "sealed" and water-proof like the Surefire versions?

I have several Surefire clickies, The one in my L4 failed soon after I got it, but as someone here on CPF suggested, I put a drop of 3-in-1 oil in the tailcap, let it coat the internals, clicked the switch several times, wiped out the excess, put it back on, and it was as good as new.

My three (L1, L4 & E1B stock & w/Z68) have all worked great.
I don't know if the SF clicky problem is still an issue but if you do a search on this subject here at CPF it might help you determine that.
