These are great for certain things. The wire is really thin so they'll fit beads or pearls with small holes. The only issue that I have with them is that since the wire is thin, is has to have strength, so it's a bit springy. For instance, when you go to curl over the end to create a loop, once you let go of the pliers the loop isn't closed because the wire springs back. Wire wrapping it would probably solve this issue though, and I usually just curl it a lil more til it's closed.
