One small observation with the instruction manual. it says
Gently screw the ionizer: hold and turn the plastic cap to screw the ionizer into the sticks dedicated ionizer shaft.
Use the plastic cap cart as a grip to unscrew the ionizer from the sticks body when needed.
Inserting/detaching a cart
Plug: Plug a cart into the ionizer until it clicks. Screw the ionizer with attached cart into the sticks dedicated ionizer shaft.
Unplug: remove the ionizer from the ionizer shaft. Unplug the cart by simply pulling the plastic cap cart out.
I'm not sure it is a good idea to twist a cart as that tends to lead to the cart turning and wool getting caught in the atomizer which then melts, I would say only do this with a blank mouthpeice but it reads as if you can do this with a full cart.
