The needles convince ...

Although I have no means of comparison, as I have previously been tested no other Jean needles, but these seem very stable here definitely. To date, no I is terminated, even if thicker denim three or four layers (seams) is processed, although I have now used has often. But the needles are really only for very stable materials. Last time had forgotten to change the needle again, and there have been "huge" holes in my smooth thin cotton fabric; -s But that's more a problem of self-organization ;-(

Conclusion: Buy recommendation!
