Review on Janome 8002D Serger Machine by Karla Richter

I wish I could return it as soon as I had a problem. I'm not new to sergers and I primed and reloaded this machine, changed the tension, did EVERYTHING EVERYTHING and it still gave me a crazy stitch. I left it for a while and worked on another machine. I came back to this today thinking I won't get up until it's right but NO LUCK. I AM SO DISAPPOINTED! I've been looking for a way to return the thing, but I think it's too late. I will never buy a sewing machine again unless I can sew on it first. NEVER AGAIN.
