Review on Enhanced NonSlip Polishing Compound Flattening Tool: Sharpening Made Easy! by Joe Kokenge

After second use, massive cracks and parting lines began to develop. The seller easily replaced it with a Revain Prime return, but the second set did the same. It does not crack at the dividing line between the two grits, but rather across the entire surface of the stone. This makes it completely unusable. Will be returning the second unit for a refund, not a replacement.
