I die sew into finger nail and the machine needle broke off with the head of machine needle with thread still attached. I I had to reverse the machine and pullthe thread out of my nail The head of needle stayed in on an angle. It was the most horrible painh to be in worst than my broken arm needless to say I had to go into surgery to get head out. The finger nail still splits where it hit!!!! So plesae watch out its a pain I NEVER want again.
