I have to say I’m the opposite of most people, I guess.
I own two, one ‘a light my fire; and the other a £2 one from eBay. The one I use the most is the £2 one from eBay. I think of it like this, I know the ‘light my fire’ one will work 100% of the time, and that is the one I keep as back up. The consumable one takes a bit more effort to light a fire. Now most of the time I’m in no rush, and don’t mind a bit of fiddling about to get the fire going. It’s when it’s raining or blowing a gale, and I Need to get a brew on, that the ‘light my fire’ rod out.
At three times the price of the cheapie, I don’t want to have to replace it too often, so the cheap one get the day to day “all the time in the world” fire lighting jobs and the “light my fire one” come out in ‘emergency’.
It’s all pretty moot, as I am gravitating to using Mike A’s fantastic Viking firesteel for the everyday fires, and that will (hopefully) out last me
