I have long wondered whether I need a serger and then some. The W6 was talking. For Gritzner 788 sprichen the additional feet, the free arm, the threading, the tension solver and the receptacle. The machine is supplied with 4 small cones that are already threaded. So you can start right away. So this supposedly difficult threading omitted. Except it's like with me ... the thread breaks. So I had to thread the same and that is really easy with the description and the threading of the hook. After the first time it can be. 5 minutes later I wanted namely sew properly and not just try, so I needed a different color. So everything again threaded. Went ratzfatz! Seam pattern is good, service is easy. I am happy that I have finally bought. Now my clothes are really ready viiiel faster and the seam also extends really. I've sewn cotton fabric, Jersey, Sweat and terry. Everything was great!
