I have one of these machines for my personal use at home. I make a lot of different things, from crafts to clothes. I also do reupholstery work at home with my sewing machine. I use to sew in a factory for fifteen years. I made RV furniture, chairs and sofas. I also worked for a boating company and made boat covers and boat furniture. I have sewn vinyl and leather furniture. I have sewed vinyl and leather with my Consew CE-200 Quantum Futura Computerized Sewing Machine. It handles heavy fabric, vinyl and leather without any difficulty. I don't have any problems with the machine breaking down. I have had it for a couple of years and have not had to take it to a repair shop for any work. It has an operating book that provides direction for the settings and any minor problems which I have been able to correct myself without any difficulty. I would recommend this sewing machine to anyone who does a lot of sewing.
