I've had my Alto's for years and LOVE IT!!! :))
I can do angles precisely ... I can do straight cuts easily. I don't have to try to hold a ruler as it only had one pressure point on the cutting guide. With my arthritis I use my palm to hold that in place and my hands don't hurt anymore.
I have even take it with my on retreats when we have to cut material there. Though I do wish all the cutting were done beforehand.
There is no wasted fabric as with the AccuQuilt GO.
