These stones are reasonably priced and seem acceptable at first glance. What I noticed when breaking the stones is that the numbers are written in a different script and the 1000 stone is just as coarse as the 200 stone, the 400 and 800 are the same grit while the 500 is better than the two. I think someone just took 6 bricks out of the bucket they fell into from the conveyor and randomly labeled them, or maybe they're defective bricks that didn't pass quality control for a more accurate set and took them out of this one bucket taken. Also, the legs that go into the holder have been beveled on two of them, causing the stone to twist slightly and not sit flush when you place the stone holder on the blade table. Cheap enough but it won't be accuracy but any means and that's why I bought this system. I returned this and bought a set of 3 diamonds from Gritomatic for $36. They are well made and work flawlessly on the Edge Pro.
