leaford, thank you for your reviews they are enlightening. I noticed on your first video in this series that really the vapor was not great even with new battery and atomizer. I was sitting here puffing my generic 901, with a regular cartridge, getting twice as much vapor with a regular cartridge. Maybe its because I don't inhale as deeply as you, so more vapor comes out of me lol. I too would be willing to replace an atomizer for you in appreciation of these valuable reviews.
