Bought this machine based reviews so, when my 1st machine broke, I figured it must be a fluke. The timing mechanism on the 1st machine quit working after 4 seams. 2nd machine made it through @ 5 projects and the feed dogs quit working. I noticed that once lowered, they were hard to return to the appropriate position on the 1st machine,again, thought it was a fluke. Sending it 2nd back and getting a Brother. The the machine is loud and shakes TERRIBLY when at full speed. VERY DISAPPOINTING!!!
