Turboflame Phoenix II lighter, yellow

I bought one of these about 12 months ago and it worked hard but seemed to give up the ghost recently as however I bled it to get rid of any air in the tank, it still wouldn't work. I bought a new one and that did exactly the same thing right out of the box! I still haven't managed to make it work so I've gone to a much more expensive turbo lighter which will hopefully do the trick as I don't have any time for kit which fails to work.
