Warning. Do not use the pipette to flood the nebulizer to prime it. The instructions included in the Kickstarter version instruct you do to just that, but if you do so, alcohol will leak out and possibly damage the nebulizer. Yep, I'm the one that did just that and reported it to Polymaker. They came out with a video explaining what you are supposed to do. After I let my unit dry out and tried to use it, the nebulizer warning light turned on. I had to replace the nebulizer with the second one contained in the box and then it worked. This time I primed by using a wooden skewer to place 5 drops on the nebulizer,
