On the day of receiving this machine I was excited, until I started to sew and nothing was working right, the tension would not work, auto tension would not work, good sewing was going on the bottom, so turned off machine and tried it again later that day, finally got the tension set, sewed for 3 days then decided to change the stitch length which was a big mistake, could not get the tension to work so I sent the machine back, now waiting for another one, same machine to see it this happens again and if it does I will be returning it and not buying another one.
