My sister bought 100 of them n line and every single one of them was horrible.
holes out of round
groove not straight
some had burrs in the eye
some just broke or shredded thread for no reason
she bought them cheap and did not check them until later so was not able to get a refund
If you buy 100 needles I would be looking at closely at one of the packages to see if there are any defects and test sew with some of them
THAT said... we have both gotten them at other times and the needles were just fine - every last one of them.
