Got this as a Christmas gift. Have used it twice since then for little things. Seemed to be fine. Decorative stitches worked and the straight stitches turned out good too. But didn't last. Just took it out to use on a bigger project and it just stopped sewing. The foot pedal wouldn't work at all. The back stitch button would sew though. If you tapped the pedal aggressively at times it would delay and then jump forward 3 stitches and then display the C3 error code saying the foot pedal was disconnected, which it clearly wasn't. Tried the Singer CS line. Was caller number 20, was on hold for 40 mins when I finally got down to caller number 4. All of a sudden the operator hung up the call and stated "their offices are now closed." I was furious. Needles to say, it went back to WalMart and I won't be buying another one.
