Just starting to get into cigars and bought a sampler online that had a Tornado Single Flame Torch Lighter and a Vector Jetz Single Flame Torch Lighter. Never used a torch lighter and had some questions.

When I release the button, the flame dies slowly. Is that normal? I was expecting the flame to instantly stop, just as quickly it lights. In fact, both lighters keep hissing after the flames is gone.

Both lighters went out when after 5 seconds of the flame burning. The Tornado has seemed to fix itself and will burn as long as I hold the button, but the Vector is still acting funking. I'm thinking I have air trapped in the fuel reserve and that is killing the flame and the Tornado has purged the air by me constantly testing the flame. Or is this a sign that I have some bad lighters?

Also the Vector Jetz has a rattle when I first got it and shook it. Still has a rattle after I filled it up. Probably a bad thing?
