The tips are easy to attach and remove from the cables. The cables are flexible, relatively smooth at the joins. The tips are sharp enough to do intricate work but not so sharp that they pierce my fingertips.
First, I bought Addi Turbo Clicks but exchanged them for the Lace Clicks because I could not do intricate work with the blunt Turbo points.
I LOVE the Addi Lace points. They are so easy to connect to the cables and the join is smooth. I tend to knit tight, but I have had no problem sliding the yarn over the connection between the cable and the metal point.
I would highly recommend these knitting needles.
