Pretty good, but not perfect. Some son sometimes break when inserting them in the slot, as it takes a little force, and it is not simple for the elderly (not too me, but I ' did test ...) attention too, during use, not to force too much, wrong, when the needle penetrates into tissue rather hard or thick: I managed to break a head. But ultimately, given the price quite affordable, these needles deserve to be included in a sewing kit.
