I have a GLV2 coming with the 5v head and a resisted 3.7v head .... I am guessing it will be twice the battery life with the 3.7v since I'll have 2 CR123s ..... ? (I am probably dead wrong. LOL)
vapn - I wanted one of the smaller Precises (16440?) in a bad way .... I was looking for the earlier ones with the brass bands, end cap and head .... now I only see all ss ones, or with just the brass button.
The brass ends really look nice in pictures, but require lots of cleaning to keep looking that good plus the threads in the atty connection wear out. The new all SS one is really the way to go for a super reliable device. And the nice thing is the SS device looks awesome with ANY of these Trippy Tips.
