This is my 4th Maggie Hoop purchase. I love this hoop. I have a RICOMA TC1501 & it fits perfectly. All I had to do was measure the width of my arms on my machine & order the right width size. The magnets are very strong. The hoop makes doing larger embroidery sizes that my 6x9 couldn't do & my larger size was too big. This fits the sizes perfectly. Saves me on stabilizer by not having to use too much by using my bigger hoop. I will be purchasing more from MAggie Frames. Great customer service & the shipping along with tracking info kept me informed.
