Just got my V1 back today and I am uber happy. It is 3.864 (I sent it to them with 3.863) and POP was on when I fired it up. I haven't had much time or any encounters to compare it to 3.863. I'll post up my thoughts here if something comes up.
Plus, I met a bomb-ass girl named Lindsey in Subway and I got my V1 back today, so it was a good day!
