The one on my Bernina embroidery machine I can operate. The one on the new Bernina 220 I bought just doesn't work for me. I love the threader that came with my Bernina 1260. It is a little thing that slides into the side of the machine when you are not using it. I hope they still sell extra ones. I mean to buy all that the dealer has so that I am never out of them.
I think the reason they put the automatic threaders on the machines is so you couldn't use the feet from machines without them. I probably have fifty feet for my 1260 that won't fit the 220 for that reason.
