I love them, the price is right, they are a great size, they throw a good amount of sparks, and they have the BSA logo on them. What is not to love? <img src="/images/graemlins/wink.gif" alt="" /> As to problems with them, they arn't as big as the Swedish firesteels so they wont last as long, but you can buy 5 of them for the price of the larger swedish firesteel model.
