I have them for my PR-650. They are great. You can embroider more because of how it attaches to the machine. It is fabulous.
I have the magna hoop for the Janome 350. I hardly ever use it. I have not used it once in the last year. The size of the inserts to me are hard to fit the designs in. I am not buying it for my 11000.
The inf. comercial looks very good, I called the comp.. but they do not have it for my machine!
