I had one and it was a decent little machine, just too small for me. I gave it to my niece and nephew for them to learn how to sew on.
They used (and abused) it for a couple years before they finally killed it. Now it gets an error after about 5 minutes of sewing; if they turn it off and back on they get another 5 minutes or so before it dies again.
So....that's sort of a mixed review, but they really did abuse that machine - I know for a fact they sewed cardboard with it at one point. It's just disappointing that the error is a computer error, the mechanicals of the machine still seem fine. If the machine didn't have a 'brain', I betcha it'd still be working fine.
