Well, I use Boye Needlemasters, but I use them less and less. The threading of the inside of the needles gets worn out so easily and I find that while knitting, (this isn't ALWAYS the case) the needles untwist and sometimes my work slides off the cable without my knowledge. So I have to keep twisting the cables to get them to be stable.
However, I can take the individual needles to hobby lobby for an exact exchange with no questions asked.
One of these days I might get another interchangeable set, but I am liking separates for now.
