That these coils in the W6 machines fit, does not mean that it can be used to pass in those without risk. In the picture, in my opinion can be seen to the original coil, which is obtained, however, are much less expensive-looking coils that are much thinner at the edge than the original coil, which allows them to burst during spooling. They also sit if they survived the winding, much too loose in the lower thread chamber, thus there may be serious problems during sewing, the thread tension can not be adjusted then, you can rotate, much as you want, nothing happens. "Fits W6" is definitely an apt description. From "Original" is indeed nothing. Also correct. However my wedding ring fits in the W6, and anyway I do not put him in there, precisely because it is not suitable. I advise the purchase of these coils from definitive. And in the event that this review appears again even if the seller W6: I definitely ordered MirjamMcFashion. Why these two articles related here, I do not know. I have submitted a also a seller feedback to MirjamMcFashion that this is not been positive, can be thought to this review. But again to understand: Please watch carefully when you want to order these coils, because they are offered by W6 really the original.
