Having had these needles in a larger size, I wanted to get other sizes for sock knitting. On the smaller size circular, such as size 2, the joins are not smooth. The yarn constantly catches at the join. I'd bought two, as I knit socks with two circulars. I really tried to make do with them, but just couldn't. Thought maybe I'd rec'd a bad set so re-ordered. One of the two new ones had the same problem. It is pretty clear the manufacturer has not yet discovered how to have smooth joins on the smaller sized needles.
