Works great for polishing smaller or lighter metal items. Not the best for heavier items as it tends to cause small scratches.

Product works well, however it gets stuck inside the casings and has to be dug out.

Currently in my tumbler as a filler for the rocks I'm tumbling. So far so good.

So far it has done exactly what I expected for cleaning up my aluminum parts, and stainless screws.

Bought this media to finish some plasma cut parts. The media de-burred the parts and removed the edge sharpness nicely.

I really liked the color and the little pyramids were all so even I used them for putting on the floor to stop the kids from running around after bedtime it really hurts when you step on them

Je commence la fabrication de bijoux en verre de plage mais , heureusement pour notre planète , les plages du Quebec sont de plus en plus propres!! Alors j’ai acheté un rock tumbler afin de fabriquer mon propre verre dépoli! C’est pyramides de plastique me permettent de garder le niveau de mon « tumbler » adéquat afin de mieux dépolir mes morceaux de verres!!
