Mine flooded the first time I filled it, not sure if it was the way I filled it or whether I didn't have enough cotton. Put more cotton in the second time, made sure the airholes were closed when screwing down the cap then tipped it upside down to open the airholes. Seems much better. Loads of flavour, but not quite enough vapour yet. Running out of mechs until my Launcher and Poldiac arrive.
just put top cap on so thread catches, turn upside down then open air holes. keep upside down while screwing the cap on till tight
