800+feedback i have and still fell for it,  be afraid  dupont lighters cost £150 upwards  if you see a new one on ebay for £40-£50  leave it  i bought one  empty no gas  when i filled it  it leaked like a sieve  on closer investigation  it was a spurious  lighter  i had already left pos feedback  as item looked  genuine,  i know  what a fool  ,so please be careful
