If you have brazed before its pretty easy to use. If you are a novice at brazing I would get some lower priced rods and practice with them. Now I am not saying these are hard to get used to because they aren't, but some people may use up too much rod before they get it right. They aren't cheap by no means BUT if you take into account what you can do with them, they are worth it. So far they haven't let go of anything I have used them on. 👍👍👍👍👍
