Gees, my little Bear Catalytic lighter has been going strong for about 4 years now, after being refilled maybe half a dozen times with various brands of butane. That little lighter cost me $8.00 at Walmart and it's been all over the world with me.
I have owned a few refillable catalytics that have not done well after being refilled. I gave up on butane powered soldering irons altogether. They have never been reliable enough for me to count on.
