Review on 🧵 Brother SE600 Sewing and Embroidery Machine: 80 Designs, 103 Stitches, Computerized, LCD Touchscreen, 4x4 Hoop, 7 Included Feet by Carol Miller

I bought this in an open box. It had an old busted tire (the bolt that makes the tire run was missing and covered in splattered glue and dirt). After using the se600 a few times it started with the error message "Check upper thread and rethread". This happens every few stitches. I reloaded; changed the needle; coil changed; replaced spool of thread; off and on: car cleaned; all countless times the same error message every few stitches. The machine is currently unusable. I bought it because of the USB drive to transfer designs and the se400 needs to be plugged into a laptop to transfer designs.
