Mine Suck! One barely allows any air through and provides near zero vapor and the second is a little bit better.
Big difference I see is that the threads are not "Vented" in line with the two air holes all the way thru the thread pattern, So when I tighten the new Attys into the Sticks, the threads virtually seal off the air completely.
Prolly will ask for a couple of exchange attys... Not sure if this change was intentional or that the threads are supposed to be slotted all the way to the battery contact. My Sticks work great with previous Janty attys and other generic 801's. But near ZERO air flow with the Attys that were delivered with the sticks.
Here is a picture of the Issue I ran into with my new Janty Stick Atomizers
