Command arrived in due time so no worries regarding delivery. For the article itself: it is true that for the price, it should not be difficult, and I'm still happy with my purchase. However, there was an oxidized crowbar, and the box is very inconvenient: when you want to store everything, you do not know which way your feet back so that the doe box closes properly. And like most users, I deplore that there was no description (and even better for use) for all these presser feet. I found a video on you tube which is not bad and gives the instructions of some feet; it is "9 feet Presser in 9 lessons."
