And now - the reason for my dissatisfaction:
The CB hook is an impertinence. The shaking strongly, so that the needle always it is true and as a result bends / breaks. At first I broke about 1 needle per week (although I have bought the machine as absolute Einsteigerin, but discovered the same talent and enthusiasm and start immediately with difficult garments) - Yesterday I are in thin cotton fabric 2 needles broken within 10 minutes - not on substance or on foot, but on the hook when the needle was inside and did not come out - clearly not my fault (especially since I also very much a "Brother" near and me is never there for it to happen in the sewing school, clear the has a horizontal hook). Then I tore out of patience and I have complained about the machine.
In defense of the company W6: All machines with CB hook are just as bad - and these are the most under 400-500 euros.
Then I read about it the same at several stores and can write the following (hopefully helpful for beginners who can not compare):
1) Please do not buy machine with CB hook. It annoys infinite. Horizontal grab is really great - zero problems! "The gripper is the heart of the sewing machine" - was told today. From it all depends.
2) Computer-controlled machines have a more powerful engine (ie, the sewing problems jeans, coats, etc.) - I can not explain with logic, but say all sellers unanimously.
3) (formerly) traditional brands like Singer, Pfaff and Husqvarna are now the same American company and no longer have the former quality. Comes from Pfaff and Husqvarna still (which, not until early 1000 euro - including only scrap) - Singer and is generally discounter-quality, no matter at what price.
Conclusion: The more expensive the better - this principle also applies to sewing machines. Unfortunately, without exception ... If you really want to sew clothes, and not only cut 1 times in a curtain - it brings not to save - you will quite quickly become very stressed out from a scrap-machine and need a good anyway.
I hope I could help a bit those who want to avoid mistakes. Have fun sewing!
