I have a P10 and would say it's a nice, beautiful
mod, very sleek, but it hits like a 3.7V
device with a weak battery, even with an LR atty. IMHO I would wait until David modifies the P10 design so that 350 mAh batts like the AW LIR 10440 will fit in it. At the moment the AWs are too short to fit the P10. I would certainly accept one as a gift, but you will probably find yourself going to a bigger battery
mod which produces more vapor and has longer battery life. For the sake of comparison, an eGo, which is similar in size, puts out much more vapor and has a much longer lasting battery.
