Rated 3.0 out of 5 by 2 reviewers.
Rated 1.0 out of 5.0 by bad experience We have got that product via Home depot and are very badly unsatisfied. The apparently good combine of micro flush and compost unit is a total failure. The design is not good, the holes for drawers are too low (barely higher than the overflow out going), dangerously close to the "evaporation" chamber which in fact is hardly evaporating anything, compared to the liquids going trough the overflow. So the ecological point is lost. Plus the composting is not adequate because of anaerobic conditions and must end up in being of a very poor quality because of leaching. And the bad smell is spreading inside, in spite of that noisy fan that is supposed to bring it out trough the vent: Water and organic matter is a bad combination. February 1, 2011
Rated 5.0 out of 5.0 by I love it! I bought this unit 5 years ago and I love it! If anyone is unhappy with this product it's because they are not using it correctly. If the proportions of moisture, waste and bacteria are correct, the composter puts out beautiful black compost. I bought a unit for my cottage and I went a little bigger than what I would need anticipating a time when I might get to spend more time there. I empty it in the spring and in the fall. It took me awhile to get used to how much moisture to add. At first there were too many wood shavings in the compost. But after adding a bit more water to the flush, I've corrected that. There is no smell whatsoever unless you stick your nose right into the compost bin opening and why would you want to do that? To the reviewer who is not satisfied with the product, I would recommend calling the customer service line at Sunmar. They are located in Burlington (conveniently for me as I live in Hamilton) and were quite helpful and patient when I called them initially with compost woes. August 25, 2011
