Ok, I might get flamed for this...but...
Ahlusion is not the only vendor for liquids.
There are some other good ones out there, not as good, but very good. Yet it is and will be my first choice and anyone who as tried them knows why. Yet if something comes up and I get low -- whether I miss out on an order or other delays - I need to have back-ups. I have backup PV's, Vivi's & Vivi heads, atomizers,
batteries, and battery chargers as well.
Ahlusion is a fast growing business in a rapidly growing market sector. They will have problems and there is only so much volume a small business can handle. For the quality of what I get, I can wait.
Think of it this way: if you favorite restaurant closed for a time due to equipment problems or supply issues would you dine somewhere else? Then go back when they are open again?
Have a backup plan.
Ok, bring on the flames.
