      Comments about Sun-Mar 400 Autoflow 102 Gallon Compost Tumbler:

      We put kitchen wastes and some yard wastes in it. It does not feed the composted material into the exit tube very well so the hopper gets overloaded and falls out of its supports. If you want a composter, keep looking.

          Comments about Sun-Mar 400 Autoflow 102 Gallon Compost Tumbler:

          I gave the composter over one year to work, and it has never performed well. Once full it is very difficult to spin. The flimsy handle broke within one year, and now the tumbler has completely separated from the base. So we will scrap it and try another composter. While one of the more expensive composters it has been a real disappointment.

            Comments about Sun-Mar 400 Autoflow 102 Gallon Compost Tumbler:

            A great product for handling kitchen waste because of the continuous flow design. A very solid product that is easy to turn thanks to the crank mechanism. To insure success with this unit I suggest you chop up the materials you add, keep the compost moist and well mixed.

            Comments about Sun-Mar 400 Autoflow 102 Gallon Compost Tumbler:

            Attractive, easy to assemble, easy to make good compost. Rodent resistence is a big plus for denser neighborhood settings.

            The only real problem is the hand crank. It feels insufficiently strong to turn the full tumbler without breaking. In fact, a neighbor's broke almost immediately, so I turn my drum by simulaneously reaching around and pulling on the barrel and turning the crank. In a drier climate -- and if I weren't composting a lot of wet kitchen waste for a family of 4 -- this probably wouldn't be an issue.

            Overall, I'm very happy with this composter.

            Some early problems

            By Leona

            from Modesto, CA

            Pros

            • Compact
            • Easy To Clean
            • Stable

            Cons

              Best Uses

                Comments about Sun-Mar 400 Autoflow 102 Gallon Compost Tumbler:

                After 3 months of using the Sun-Mar 400 garden composter I find I am not entirely happy with the product. The cover for the outflow port is hard to close all the way, or open once closed. The material placed in the bin tends to ball up, and the material that collects in the center core for finishing dries out quickly resulting in hard medium sized balls of organic matter. Spraying water into the center core chamber is frustrating, as it all just pours out again. The handle on the crank also sheared off after 3 months of use, which is not at all a durable feature.

                It is easy to load material into the composter, easy to turn with the functioning crank, and easy to add water to the outer part of the bin as needed.

                  Comments about Sun-Mar 400 Autoflow 102 Gallon Compost Tumbler:

                  The composter is great except for the difficulty I have screwing and unscrewing the access lid to get to the compost. I can't get it to screw all the way in, which causes the rotation handle to hit it as I turn.

                      Customer Q & A

                      2 Questions About This Product
                      Q: "Does autoflow mean we'd have a continuous supply of compost? How long does it take to get our first full inner drum?"
                      A: The autoflow system allows material to continuously "flow" or move through a special double-drum setup. Heavier material settles to the bottom. Lighter, decomposed material finds its way to the top and eventually enters the inner drum.  The first production will take approximately 2 - 3 months depending on the amount of worm food you put into it.
                      Q: "How big is the opening on the top?
                      A: The opening is 10 1/2W x 12L inches.
