The issues that's been mentioned previously by the other members here?
I'm more concerned with the parasitic drain (how quickly will it drain the AAA Nimh) and if the battery switch is replaceable?
I respect your concerns. Its up to you to make the call on whether the other features of this light are compelling to you.
fwiw, I believe the concensus, after long discussion, is that the device in the switch, that charges up and is used to fire High Mode, is a capacitor, not a battery. I found that somewhat less concerning.
as far as "the issues",
the switch requires a AAA to be in place for more than 20 minutes on a brand new empty light. Also high mode is not as efficient as in the copper model. If you use the light primarily on medium or low, these are not necessarily reasons to pass up a really cool titanium light.
the switch is good enough for maukka to choose to use on the copper tool he carries. he obviously has enough knowledge to not fear the switch.
imo an AAA light with Constant Current and High CRI in Titanium is nothing to sneeze at for under $25. It does not have to be for everyone. I for example, prefer the Copper version
Do whatever makes you happy, let us know if you try the Ti
it has a great form factor imo, though I find the switch a bit small..
I really like the keyring connection, and the fact that Ti is light for keyring, and it is Shiny Bling
to your concern of replacing the switch.. by then you will probably have your eyes on some new model.. also, even if the Tiswitch fails, the light can still work as a twisty or with other Tool heads
why worry? be happy!
