You would be more likely to be able to start a fire if you assemble a kit with some wind proof matches (various brands), normal matches, and three or four Bic disposables. You should then have enough redundancy. The right kind of tinder and technique is just as important as your lighter.

I have carried a Windmill for several years and it is OK (it has never failed to work for me) but he flame comes out at an awkward angle for the kind of stove and fire lay that I usually use. I found a better lighter for about $12 at my local sporting goods store.

People on this list have lots of different preferred tools for making fire, but I am sure nearly all of us would agree that redundancy is a good thing.
