### ⭐⭐⭐⭐ Good product overall
*by J***N on July 10, 2025*

I thought this product worked well. I added it to my compost pile in Utah in mid summer. I felt like it sped the composting process up and helped make great fertilizer for my garden. Its hard to tell what impact it had or whether the compost would have broken down anyways.
