Been mainly using Old Boy's and the Pipemaster line. However, they all fail eventually and need to be serviced and this is the main reason why I went back to using matches. The problem with torch lighters is I have seen them fry the interior of the bowl after repeated use.
I am seriously thinking about getting my Zippo back out for outdoor use as Old Boys are not really good if there is a breeze going. If you let the flame burn on the Zippo for a few seconds before lighting the bowl, you can negate most of the taste from the fluid.
My wife bought me a Zippo with a pipe insert about 20 years ago. Aside from the occasional cleaning and replacing of the wick, it has never let me down, something I cannot say about the more expensive lighters. I've got 4 Old Boy and 2 Pipemaster that need serviced and with the exception of the one I dropped, the others have worn out from use over time.
Arango wants $35 per lighter now for servicing so it is getting expensive. Plus the black matte finish wears off over time if kept in a pocket.
Stay away from Colibri. Have seen too many of these returned within days or weeks of purchase. I would also recommend staying away from the Xicar clone of the Old Boy. Their flint tubes are not secure and I had to return several because the post kept breaking in my pocket. They have a lifetime warranty, but after the third one I gave up. Nothing else in my pocket either.
