Peanut lighters are definitely a bit more fiddly that a bic - IMO.

I bought four (cheap ones) a while back and one did not work ! But I guess you get what you're paing for.

A plus with the peanut lighters is that they are easy and unobtrusive to attach to a key ring - as an EDC item.

Also you can light them and stand them up - like a candle, which is also handy if you want a light or need a candle.
