They look good and can be assembly and disassembly without any problems. Knitting is pleasant. It has a wide range of different needles in a small space.
But so far myself every major piece of knitting has cost three ropes. They break just behind the screw. I must say that I'm in my "shell and cardigan phase" and really at least 1000 g - pieces work. Maybe the weight of the needles can be enervating. Slowly that is expensive and is really annoying when you're in the middle of work and then slip all the stitches to nirvana.
As I said, I find it much nicer and more comfortable than conventional needles, but so durable they do not seem to be. In the thin needle sizes I had multiple needle breakage.
For smaller knitting pieces you have not the problem of possible ways. Here in the north weak consumption, they are also very difficult to obtain.
