If you consider yourself to purchase this unit I say only one thing: do not buy! I have long considered around, there were 1.2 halfway positive comments so I looked on the reviews of time and ordered the part. Finally, I needed it so only now and again can sew on thin fabric to a halfway straight seam. Until now, I was doing the always manually. I wanted to save time, be faster. But there is MAN FAST; IF YOU SEW manually! Too bad! The manual is the horror, it is three small mini pages short, does not contain any relevant information, this will be described in detail how to load the batteries. In addition, the instructions are not even properly translated into German.
It not only always tear the threads, but certainly their nerves! I sat next to a half-day and I managed to pick up only ONCE the bobbin thread. That alone would be enough. When I tried to sew, the haute well not go. Although it looks nice, but is to be thrown away. I hope I get at least refunded everything. Take it seriously: do not buy!
