I've been a Kannastor user for right around 20 years, when I bought my first 2" grinder, I knew I wouldn't use any other grinder again... RYOT employees have been help on several minor issue I've had in the past, IE. screen replacement for the original snap ring application to replacement of a faulty EZ change tyne for a solid body 4 stage grinder to purchases for this year christmas presents for my friends, thanks to them all!
