I wasn't happy with results. So looked into different grit. I only used the shine grit ( last stage) on the rocks that had already been tumbled with a shine grit and I was surprised at the difference. I haven't used the others but I'm sure the quality is just as good. Review: Worked as advertised - I'm new to rock tumbling, I've used a few different polishing grits and this is the best one so far. I ran this polish cycle for 7 days and am happy with the results. ## Features - COARSE, FINE, PRE-POLISH, AND POLISH KIT: Get the ideal results with this professionally-graded kit, starting from coarse Silicon Carbide Grit for quick stock removal to a finer Aluminum Oxide Polish Grit for a perfect finish.
