Bests & Worsts Reviews from Amazon

I have purchased two machines of this model, and they both broke with the same problem, the timing. They were only a few months old, too. The thread on the reverse side was all gathered and messed up. I gave up on Singer and bought a Bother sewing machine. As I was loading up the Singer to discard, I thought I would try YouTube to see if there was a way to fix it. There are videos. I tried the repairs, but the problem persisted. The 4411 model has the feel of a solid machine for the price, but unfortunately, I received two defective ones.
