Don't get me wrong, I love what they do. It has helped a bunch of my river rocks fet that extra oomph. However, when the Nat Geo rock grit kit with all 4 grits, and ceramic and the 1 Oz of this foam tumble media is only like $5 more, this feels like a money grab rip off. There should be way more foam pellets if getting this singularly.

I have only done one round in my tumbler, and one for a few days. But there was some shiny rocks already. They work great, I wish there were a few more cubes so I could do bigger patches but, theyre awesome
