The MJR Tumblers 3 LB per Polish Sub Micron Aluminum Oxide 12,000 Extreme Polish Rock Grit Stage 4 has received a generally positive reception among customers who use it for rock polishing. Many users praise its performance, noting significant improvements in the shine and smoothness of their stones. Customers have found it especially effective for softer materials like Montana wonderstone, reporting that the results are markedly better than with other grits labeled as "pre-polish." However, not all feedback is wholly positive; some users noted that the polish can leave a haze on the stones, even after burnishing. This inConsistency suggests that while the grit is capable of achieving high-quality results, it may require some additional techniques or precautions to avoid undesirable outcomes. Overall, customers appear to appreciate the effectiveness of this product for reaching a high level of polish and recommend it as an essential part of their tumbling process, particularly in cases where other products haven't delivered satisfactory results. Nevertheless, the slightly higher price point does give some Prospective buyers pause. **
