My new 820 came with an update kit that included everything EXCEPT the rectagular metal stickum piece you refer to. I was worried that I should have exactly the items in the kit, but I've been sewing along without it with no problems. Did you get the little booklet explaining the use of the items in the kit? I think Bernina assumes a level of knowledge, expertise for each machine model, and service that not all dealers are willing or able to provide. I'm still struggling to get 1/4" seams with the ease, accuracy, and consistency of my 440, 930, and BabyLock Quest Plus. I've tried the 37D and 34D feet and the ss, 5.5mm, and 9mm plates and various needle positions. While I can get an accurate 1/4", it requires much more guidance than I think it should based on my experience with my other machines. Otherwise, the 820 is light years ahead of anything else I've ever sewn on and I'm enjoying it immensely.
