I must admit ... I forgot most of their birthdays
some are so old ... they don't care anymore ... they're just happy to be sporting a freshly loaded Kayfun
you know, with all the young better looking Provi all around
It's kind of funny because I only did it for the "Core Four" Provi's, and not for ANY other mod (including the two newest Provi's, Ti & GMZ). I actually put it on my calendar, mainly to track how much time I got for my investment.
I'd just come off my initial six months of vaping, and had gone through a TON of 808 batteries, a couple of Go-Go's (I still miss those Go-Go's), and one Lavatube.
When I realized just HOW well built they were, I got a 2nd (shortly after the 1st, and the newer "Black" that had JUST been released). Within a year I'd purchased two more (got to have backups!), and sat with just those four mods for quite a while (well over another year).
As it turns out, I could have hung there until even today.
Phenomenal devices. Simply phenomenal.
