KA interchangeable needles

I have been searching for an interchangeable knitting needle set. Unless you've been under a rock, you have heard about knitpicks options. But I really don't like so much color going on in my needles, and the storage system is lacking. So when I saw these KA BAMBOO CIRCULAR NEEDLE Set, I had high hopes. They have a nice environmental statement. My only worry is the quality of the joins.
