Yes there was a batch that wasn't annealed properly. Somehow they slipped thru their QC. Common problem is what you see here too hard the end just snaps off. If you have a set you would like to have checked please send them back to me. I will take care of it for you. Sorry for the inconvenience.
FYI the manufacture just upped their price on each part by $50.00. So that puts my cost at $750.00 plus shipping almost what they sell them for. Don't forget I need to buy 10 parts at a time.
Thanks Joe
