Query: Defective or just not a good product?

I had such a terrible time with mine, I am returning it. The thread would not stay threaded right no matter what I did. But the biggest problem was that the screw holding in the needle will not hold it in. It won't tighten enough to keep in the needle. So I kept fixing it and it kept falling out. I struggled with this machine for almost an hour over multiple issues. Finally I am giving up. I will stick to my good old Singer.
