If that's the worst sharpen your local place puts out, consider yourself fortunate.
Ive been sharpening for 15+ years, I'm sure this Sparx will find its place in the niche markets, just as any other upstart product does. However, people who try to remove the element of human error also eliminate the element of human correction, which I submit is necessary to the art of skate sharpening.
I'm curious as to how these machines will hold up durability wise, and how long-term calibration of them will be handled. I find it hard to believe these machines can sit in homes and sharpen for any length of time without requiring some maintenance.
