I Have 2 Screwdrivers & 2 chargers in use.
6 Spare Atomisers + 3 in use.
8 Spare Batteries + 3 in use .
30 Empty carts + 1 in use
200ml Liquid .
It is always good to have spares but if just starting out buy 2 kits and maybe 1 spare atomiser.
If you are a bit short on funds.
Each week buy another atomiser with your liquid order and build up slowly .
My atomisers live about 2 weeks
vaping about 40ml Liquid.
If you are in habit of rotating your atomisers they may all die at the same time.
