the 25 MM version i bought to go on a mech
mod is basically unusable for me.the design is best used on a squonk
device becuase it is nearly impossible to drip evenly and effectively without popping the cap and giving it a few drops on each side back and forth until you get it saturated again every 3 hits. goes on the shelf until i need to make room for another atomizer when it gets stripped for parts and goes in the bin.
