@scoop, I nebulized 7 ml of 7%this AM without any leaking, not even any drop falling on my hands. I hold the device somewhat straight. I can see there is a little bit of liquid in the mouthpiece, butfor some reason it is not falling out by the openings. The blue light was not triggered today. But it has twice since I got it, the maintenance is really easy to perform. I do believe you might have gotten a lemon. This has been working extremely well so far for me. I hope you get it replaced by Amazon.
Best wishes of great health to all of us!
