It does have a separate atomizer, similar to my 510 and Smoking Everywhere models. The cartridge though deviates from the plastic cup with a ball of fuzz design. About half way down, there is a doughnut shaped ring with a small hole in the middle. They are not easily disassembled like the others, so I'll have to cut one open to see what they use to hold liquid.
Another unusual thing about this model is that there is no whistling of air, no shaking it this way and that to get it going. It does provide a steady consistent stream every time.
