      Excellent!

      Posted by Richard on Mar 2nd 2026

      My old Sioux 620 had the worst setup until now. The new stone dresser is way better. Unfortunately, like the old one, there is no direct way to align with the slot in the machine. However it is far better to align and the existing stud was just long enough. 100% better and very well made!
