For starters the The Doors didn't write a song about them <img src="/images/graemlins/smile.gif" alt="" />

I cant comment on Light My Fire because I havent seen them. However my couple of Magfires are very good. With my small collection of firesteels (I know, I need to get a life) I would be hard pressed to say any of my others are equal to them.
The only reason I dont EDC one on my keyring is that I have a physically smaller sized firesteel on the keys. My keyring is way too big as it is.
