### ⭐⭐⭐⭐⭐ Polishing rockd
*by D***A on May 12, 2026*

Easy to use

### ⭐⭐⭐⭐ Tumbler works well, but far too little grit is supplied
*by J***N on March 13, 2022*

The tumbler works well enough, it's very reasonably priced, and generally a good kit. The rocks that come with it are a good starter; there are some findings included for finished rocks; and the instructions are reasonably good (accepting some significant caveats below). There's also an included strainer, but we found it much too small, and just used a small colander from our kitchen. Accepting the good points, there are a few important things to consider: 1) The kit comes with a paltry amount of grit. We followed the instructions to the letter using the small grit packets provided in the box, and just couldn't get a good polish on the included rocks. However, we had also bought a set of additional grit at the same time, so we re-ran exactly the same rocks with proper amounts of grit and got a beautiful polish. The additional grit was exactly the same grade and composition as the original, but its instructions called for 2-3x more grit per run. So, I expect a lot of people will be underwhelmed at the polish they get, not realizing that the minimal amount of grit is likely the problem. Since grit is a consumable that you'll need more of anyway, you can save yourself a wasted month of tumbling by buying more grit and just topping off what comes with the kit (2 tbsp for stages 1 and 2, and 1 tbsp for stages 3 and 4). 2) The tumbler runs fast, even at its slowest speed (seems at least twice as fast as the tumblers I'm familiar with). This means it's on the louder end (we kept it in the garage) and it doesn't seem to do a good job on more angular or larger rocks, because the tumbling action is just too aggressive. Anything under 3/4" diameter and/or mostly round will polish up great—which mostly included the rocks that came with our set—but anything outside that ended up with some unpolished edges (although the smooth/flat parts still polished up well). That stated, you can cheat and use mineral oil to mostly hide the rough edges, but they still won't look as good as they do with a proper polish. (Although, I haven't yet tested if ceramic media or poly pellets could improve this situation by cushioning the rocks during the final polish stage.) 3) The instructions could be better with respect to cleaning, and don't cover burnishing at all. For cleaning between stages, after a thorough rinse I strongly recommend putting the rocks back in the tumbler with warm water and a drop or two of dish soap, and then just running it for an hour on its lowest speed. This will clean out all of the grit from the last stage. Then just re-rinse (the sink is fine in this case, since there's so little grit) and start the next tumbling stage. You may want to burnish as a final step, to get a better shine. There are a number of good guides available, so I suggest just searching for the term "rock burnishing".
