Overall this works well and is easy to use and functions well. Sun Mar customer service is quick to respond and helpful when questions came up during set up.
4 stars because of the maintenance costs (microbes, enzymes, compost matter).

This is my second go around, I have been using this product for 18 years. This product is an excellent example of living off the grid and leaving a small and sustainable foot print. Sun Mar is the best. Now I will have 2 of them.

This is an additional second one we have. The step is of no value, make your own wider and longer. Really good for a cabin.

Sunmar NE is reliable and odour-free
Our first Sunmar NE is still going strong after 25 years but we needed another for our new house. There is no smell and no need to clean anything disgusting. You just turn the mixer drum to extract clean non-smelly compost every few months. Makes happy tomatoes.
