What will make the P16 nice for regular 510 atomizers (non LR) is that with a good AW protected LI battery in place (750 mah) you will be getting about the same vape time, or better, than many people do with the underperforming 14500 Trustfires,Ultrafires, etc in larger mods. We will see how it does using LIMN's from nhaler (rated at 450 mah) and AW (rated at 550 mah) and those Eastmall 510 LR atomizers that showed up the other day. Meanwhile, I wait patiently.
