Grandson is happy again.
Purchased a rock tumbler for my grandson. He has used it a lot and needed more media. This kit is exactly what he needed to continue his cleaning. Very easy to use.

Decent Value for Hobbyist
These are the same grits that come with the tumbler kit. The scoop that comes with it is a nice addition. I've found that some grits get used faster than others, so it may be worthwhile to find a supplier that sells individual grits. Depending on where you find your rocks, you may find that some of the heavier grits are not needed as much as the finer grits. Most rocks I've polished came from riverbeds and are fairly smooth to start with. In my experience, you can start with the 3rd grit on these and still get the desired results in less time since you can skip the first grit or two which is about 2 weeks of tumbling. Another tip, get some dishes like cake pans or casserole dishes at the dollar store and pour the water/grit from the tumbler into them and let the water evaporate. I have one pan for each grit. You can then reuse the media several times before discarding it.
