Rated 5.0 out of 5.0 by Best Compost BIn you can buy!!! It is exactly as all the rave reviews I read on Home Depot's online store said it was!!!!!! Easy to assemble, Easy access,! We love it!! So easy to turn your materials with a pitchfork, stays sturdy to the ground with the stakes provided. I had it shipped to the Home Depot nearest me to save all shipping costs and that could not have been easier!! April 8, 2014
Rated 5.0 out of 5.0 by Always the best for all season composting! I love this product. I have had several of these over the years and it composts evenly without the need to turn. I especially appreciate its size and how much it fits so that I can compost all winter (and winters last a long time in Chicago). In the spring/summer, there is luscious compost on the bottom that is scooped out from the trap door. I highly recommend this bin for its value and performance! December 10, 2013
Rated 5.0 out of 5.0 by Best Composter on the market This is my second Earth Machine. We had one at our old home and stupidly left it behind. When we moved to our new home we bought one of the ones that is a barrel thinking it would be easier to maintain. WRONG!!!!. It was smaller, filled up much quicker and did not compost well. I missed my old Earth Machine and searched high and low for another one. The only place that deals with them, other than some county and city operations, is Home Depot. The unfortunate part of having to but it through home depot is that they charge as much in shipping as the cost of the composter. The composter works very well, add a bucket of water every once in a while to keep everything most, more in drier climates like mine in the Central Valley of California. The compost happens very quickly and you will soon be utilizing some of the best compost money can not buy. It will also help reduce your trash as all the vegetable cuttings, garden cuttings, lawn clippings, etc can be utilized in your compost. March 19, 2013

Rated 5.0 out of 5.0 by This composter is just what we needed. Very well constructed. Critter-proof. Easy to use. May 21, 2013
Rated 5.0 out of 5.0 by Our NEW Composter I know it will be a great value as we have just begun our walk down that recycle path using a garden we created and now implementing this to create good enriched healthy soil for our garden not filled with pesticides and stuff. Its easy to use and I know we will have it for years to come. August 21, 2013
Rated 1.0 out of 5.0 by JUNK! i received this as a gift last summer. I did not use it at all this winter and last week started putting fruits and vegies into it. the vents are close to the ground and within 1 day, an animal had chewed through the flimsy vents and made a large hole. I called the company and nobody answered the phone. I emailed and said they would replace the piece for $25 plus shipping. I had a different compost bin for 20 years and never had anything like this happen. product has a 10 year seemingly worthless warranty. March 20, 2015
Rated 4.0 out of 5.0 by So far, so good. The unit was easy to put together and seems pretty straight forward. I added some Ringer compost plus to the mix to hopefully speed up the process during the winter months. This is my first time using a composter. In the past, I've made composters from old pallets, which worked just fine. However, I'm in a development that is a little more upscale and I don't want to upset the neighbors with anything that may seem junky to some people. This unit is black and does a good job of "disappearing." I'm happy with it so far and it seems to have room for plenty of material. It's not a barrel, so there is some extra effort to turn the mix and keep it cooking. I've been using a pitch fork and it's fine, but a nice workout nonetheless. February 10, 2015
