Would probably last about 2 seconds coming from.China.mate. Your better off just going to bunnings and getting the bernzomatic propane bottle and it come.with a torch. About $25. Every one uses them.
Edit; are you talking often soldering or hard?. Doesn't work to good for hard soldering, you need mapp or oxy.
If you're looking into soft soldering, pick up some AquaSafe 100 solder while you are there. Don't get sucked into buying the overpriced Bernzomatic stuff :handgestures-thumbupleft:
