I was just wondering if anyone has any experience with a Med-Fit Micro-Neb Rechargeable Portable Mesh Nebuliser? it's fully charged and everything is connected. the problem my wife is having that when she switches it on it lights up but then nothing. I have taken off the liquid chamber and re connected it, but again nothing.. Even tried it being plugged in but still the same. Does anyone have any ideas what else I can try please?
