More than plenty. They last a long time. I've used them for ages and very little problems but they are not completely foolproof. The action on one froze up on me one time and nothing could fix it, beating it on a piece of wood or rock, nothing. But I've also used some for years with no problem. I take some backup now just in case but always use the Bic. I keep mine in an old bicycle repair kit box with a BSA Hotspark for backup. I like to take some ultralight UCO matches too. But again always use the Bic. It is just too convenient.
