That's a good reminder to follow the directions!

My theory is that the gold contacts on the InnoSpire Go nebulizer need to be cleaned with rubbing alcohol after each use to maintain connection. And using a baby bottle sterilizer is verboten. It seems to warp the plastic a bit and who knows what it does to the mesh head. The instructions explicitly say, "no steam sterilization". I have 2 still in top notch condition, thankfully. They get boiled for sterilizing.
