My opinion is that the seller is selling an illiquid product. Very upset that I wasted 1300. If I knew, I bought a similar disk (Chinese) in Leroy for 900, and it would be better
Cons
There is rust on the disk, nothing terrible, of course, but most likely it was lying around for a long time (undiquid). When I unpacked it, I first turned to this rust, and then when I put it on the grinder, I saw that the disk was CURVE. Of course, now no matter how you level it, the beats will be present.
