Skipped a step
I bought this set when I first started tumbling rocks. The grit works well. My only complaint is that I got 2 bags of the step 1 grit, 1 bag of step 3 grit, and 1 bag of step 4. I didn't get any step 2 grit.

MAKES TUMBLING ROCKS SO MUCH EASIER
This grit works just like all others, if used correctly. It is so easy to open and pour it into tumbler--the perfect amount for a 10-lb tumbler. Highly recommended.

Misleading description
Quality aside...the amount of product sent is not what I thought I was getting. My fault for not reading the description better. This makes the product extremely overpriced and I will purchase a different brand next time.
