Ah - perhaps a little over the top of what's needed within ones home then.
A nice big fire engine pulled up outside our house one day and they offered to fit them free while they had nothing better to do. Nice scheme, and surprising seeing how relatively little of the council tax is for the fire and police services.
I suspected the PG level would be a factor!To stealth vape you need something not too powerful like the iStick 20w and some 50/50 or more PG juice, which will not give off so much vapour, then you can hold in the vapour until it dissipates.
...hence me wondering how on earth I could do it.I still have small 10 & 20w iStick batteries - even a few small Evod ones, but not producing vapour is another matter. Only way for me would be a cig size battery with a cartridge.

...I'd be sure to be seen!
