Thanks for the tip- I'll give that a go- I've got a cheapy turbo lighter which also keeps cutting out so I will invest in a better one and try the method you suggested :D
Hiya- now worked out how to disassemble it but got another issue- for some reason even though it's 'clicked' I'm not really getting any vapour- nothing like in the Dynavap video anyway- can anyone advise? Don't want to combust my herb lol
