I own this machine and have well over 1000 hours on it. I purchased it in 2013. The machine was replaced one by Pfaff as the motherboard fried doing a heavy embroidery. Was back in for repairs for a broken part caused by overheating during another embroidery session. Was back in again for a serious tension problem. When sewing I have not had a single issue. When embroidering the machine does great right up until it overheats. I consider this to be a design flaw with the machine. I would not purchase it again for embroidery, but would as a straight sewing machine. Hope this helps.
