Just a quick report... With a little more than a day with the new P3, I (like most on this thread) am thrilled with the device. I use carto tanks with 3 ohm cartos, so I don't get as much benefit from the boost, but I think I can tell a bit of difference with fresh cartos on both the P2 and the P3. Even with my old eyes, the menu system is easy to read without my reading glasses, and it's easy to navigate at the default speed.
I'm getting an IQ of about 91 with my Panasonic NCR 18650 batteries which seem to be lasting about 22 hours of moderate use. Overall, I'm getting a great vape experience, which is what I've come to expect from ProVape. I set it to 7.6 watts and random button LED colors (I like the novelty for now), and it just does the rest.
And yes, I will be buying another one when they come out with the Gun Metal ZenKote option!
