    Good for removing sediment on rocks
  

*by D***L on Reviewed in the United States on April 17, 2022*

I use this for rocks that have thick sediment on it. Works well so far. I keep checking rocks a few times a day in the rotary tumbler to see  progress.

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Stick to rock tumbling
  

*by G***. on Reviewed in the United States on February 1, 2018*

I am going to give this 5 stars but it didn't work for what I purchased it for.  I bought this to try and tumble sand small wooden parts.  This was not coarse enough for my purposes, so if you are buying this for that purpose, please reconsider. But as for a good review I can say it does have little dust, very consistent in its particles.  When I was using this to dry tumble (which I don't believe it is intended for) it does powder up pretty quickly.
