Yes, Viking users have a most wonderful hoop available, comes with 4 magnets and my dealer sold me 4 additional, with full disclosure of what I wante to do with them. He is the "mechanic" I trust, he saw no problem. These magnets are pretty darn strong, come really close to the computer when working, and have caused no problem at all. I use the hoop to hold a quilt (all sandwiched up with batting- too thick to "hoop") and I did stars all over for the Quilts of Valor project. Works well, no damage, no threat..as stated above, the computer is very well protected and is only a processor, not a true computer. I have set my magnetic pin bowl on top of my usb stick accidently with no adverse effects.
