## Customer Reviews

### ⭐⭐⭐⭐⭐ Very heavy duty
*by D***E on June 20, 2025*

This work wonderful and is heavy duty. Was very easy to put togeather

### ⭐⭐⭐⭐⭐ Helping the earth, perfect for turning your veggie and fruit scraps into nutritious soil
*by S***M on July 6, 2025*

I do like this sturdy composter that is easy for two people to assemble, few parts. The seller was exceptional as I sent a not-so-nice message when I mistakenly thought there were no assembly instructions. His message was incredibly prompt and kind. I apologized profusely when I found the directions in the drum of the composter rather than with the parts that required assembly. I recommend this composter. It is a bit more expensive than a few others I found but worth it. You get what you pay for.

### ⭐⭐⭐⭐ Missing parts, extremely bad instructions, but simple to figure out.
*by M***Q on April 11, 2020*

Instructions start with inserting the mythical part 'FF' through the bin. I don't have that part, and no video or review I find mentions it at all. Apparently it's not necessary. Plus, there are no actual words in the instructions; just pictures; which completely omit the fasteners. Finally, there are plastic bushings that are shows in a place in the drawing that is physically impossible unless you drill holes in them and get longer bolts to account for them.Other than that, it hasn't fallen apart yet.
