I have the Accuquilt Go and love it. I have quite a few dies - you need different size mats for the different size dies- you dont want to try to use a 6 x 24 mat on an 8 square die.....
I use most often my strip dies- can cut r (5) 1 1/2 x width of fabric x (2) at one time- so, (I) run through and I have (10) 1 1/2 x 40 perfect strips. I also have some applique dies I definitely use the strips & squares most. Its so nice to be able to cut multiples perfectly and quickly. I cut all the 1 1/2 strips needed for a king size log cabin quilt in less than an hour. By hand it probably would have taken me a week.
