Best machine of this time

Good Value, Great Features, Easy To Use, High Quality

While this machine isn't from the 1950s, it works like it is. Super heavy duty. I have taught my granddaughter to use this machine and she expects to inherit it when I finally give it up. I've used many many machines and almost all were Singers. I would strongly recommend this machine, unfortunately it's not available in our town anymore.

Poor Quality, Easily Jammed

I was really drawn by the heavy-duty title of the machine. I was looking for something strong for heavy cotton and thin leather. I bought it in december 2015, in january 2016 it had already jammed. Amazon just replaced the product no problem. In april 2016, it jammed again just by sewing 100% cotton medium canvas, lost timing and the bottom thread always gets stuck around the bobbin. The metal plate conducts electricity and I always get shocked on it. Anyways, i would've gotten something else.

I have put this product through the rest by making a quilt. I did not want to let this just sit around. It lives up to its description this far. As I am still making blocks (4 left to do). But right now I am enjoying this machine.

Adthought The Case Would Be More Heavy Duty.d A Con

Have mended on a backpack without any difficulties. Wish there were more feet included. Also works on leather, putting patches on vests and jackets.
