These circular needles worked with me for about 2 years. Used just for 4 sweaters during this period. At a then broke off the tip, with two additional needles, the cable broke off directly at the connection to the needle. I lost every time all recorded loops, for example, half of Pulis. That has very annoyed, especially since these needles should be branded. There were always affected the 8.00mm needles. The smaller sizes not go broke so far with me.
Conclusion: The brand I do not buy back, at least not in this size.
