My favorite lighter is a Mini Bic. I personally have not had one fail. I have some Mini Bics that are 4 years old and still are full of fuel. They work on the top of mountains in Tahoe. I think they are over-engineered, but their low price and throw away status causes people not to favorite them.

My second favorite is my County Comm peanut. It does not leak fuel at all after I upgraded the O-ring and really hammer down on the tightening. The County Comm peanut has an upgraded shell over the cheap Chinese peanuts you can get from DX.com, but the guts appear to be the same. The shell upgrade justifies the added cost because the cheap Chinese peanut feels like it is liable to break if I drop it.

I do not own the Tohil linked above and frankly don't feel a need to own it.
