I bought this new 3 days ago. I wanted this so bad but there are concerning issues and I have to return it. The hand wheel is really hard to turn, like it is jammed. When threading, it sounds terrible, the very first guide sounds like it will shred the thread (it doesn't though). It sews perfectly, that's why I am confused. Not my first serger so I know this is not right. Sad. I still think this machine is great, I just think I received a troubled one, it happens.
