Useful, but a little flimsy
I already had some KnitPro stitch markers when I bought these, but I wanted some different colours. They serve their purpose as well as the KnitPro ones do (quick and easy to lock and unlock, and they stay locked for as long as needed), but they are a little less substantial. I'm not quite sure what the benefit of the crimp in them is, since the KnitPro ones don't have it and they don't appear to be any different in use; but, anyway, they do an effective job of marking stitches and they don't get caught in the yarn.
