Already posted this in the Reviews thread, but I'll post it here too:
I put my hands on a P3 today! I drove down to Jackson, TN and talked with the people at Roar Vapor for about an hour. Seriously great people. They let me play with the P3 for a few minutes. Pretty much anything there is to be said, has been said, but I have a couple notes:
1. The Power Boost, is awesome.
2. Remember how long it took to learn how to navigate the Provari when you first layed hands on one? Tack on maybe an extra 30 seconds for the P3. If you are fluent moving through the regular Provari's menu already, it might take 30 seconds total to get the feel for the P3's menu. It's extremely intuitive. No offense to anyone, but if the P3's menu is hard for you after 10 minutes, you should probably just get a mech and Kick it.
3. Regarding the 510 connector coming off with the atomizer... IDK, I didn't have that issue. They took the top cap and 510 connection off, and put it back on in front of me with their fingers, without tightening up with a coin. I put my Kayfun on, the same level of snug I do on any other mod, and it unscrewed just fine without the 510 connector coming with it. (Also, that floating pin is awesome!)
4. One thing that surprised me, is that the screen seems to be measurable smaller, despite giving far more, and more useful, information.
That having been said, if you honestly believe you must subohm, or think that the single button interface is outdated, or whatever, yea, probably not the mod for you.
