I bought this machine used. Apparently they had problems too, as they sold it very cheaply, even though it was virtually brand new. I tried it before I bought it and it worked ok on thin material sample. But, when I got it home and tried it several times on thicker materials...the needle broke, the machine jammed, or the thread pulled out of the needle. I only recommend this machine to those who sew thin materials...and have a lot of patience!
