nope, it's returned. with Goodwill, you have seven days to bring it back; that's it. I disassembled and reassembled the tension/threading assemblies, tightened up the spring wires, tried slack tension all the way up to tight tension - no success. Ran fine on sloooow speeds, tangled as soon as i sped it up, every time. My mother has a serger and i can use it whenever i want, but i didn't want to gamble with the $40 i'd already spent on the machine, so it went back today. c'est la vie!
