Here Is What Reviewers Had To Say About The FCMP Outdoor 37 Gallon Black Tumbling Composter…


The Black Color Really Helps To Build Up Heat Necessary To Break Down The Material!


It’s been fun experimenting with C/N inputs and moisture levels in here, and in the summertime it works quite quickly with the black plastic.


  • And it is black, which is great for getting the heat up, even if the temperature outside is cool.
  • I spray painted the metal legs black which greatly improved its appearance.
  • It works better than promised (you just need to follow instructions). It would work even better if I put it in the sun, but my wife wants it hidden at the edge of the woods.
  • I sprayed the legs black and you really can not see it.
  • The black helps to heat things up quickly & get it working fast.
  • Easy to assemble and also easy to tumble to mix compost. Black plastic soaks up heat.
  • I did spray paint the metal legs black to make them less noticeable.
  • Thanks to the black plastic, if you keep this in direct sunlight it really heats up, which speeds up decomposition.

The separate, well-marked sides makes it easy to keep track of which side is cooking and which side can be added to, etc. I’ve tried several different systems and this is the easiest to use and to start things “cooking” in.


  • It’s sturdy and light, easy to fill and empty, and I appreciate the reminder embossed on top which tells me which side to throw stuff in when I’m tired and inattentive.
  • Easy to load and works quite well. I can’t believe how it’s cut down on trips to the town dump and just feels good to return stuff from the earth back to it.
  • It’s easy to load and easy to rotate. Great composter at a great price.
  • Very sturdy frame! Heavy-duty materials! Well thought out design! Great for loading and unloading materials, I was concerned with how small the door looks in the pic but in real life, it’s more than adequate.

  • Great height, I’m 5’10’ and don’t have to strain my back to load/unload.

A Tumbler Compost Bin That Is Easy To Empty!


Emptying it has been easy, you just turn the opening to the bottom, place a bucket or pan under it, open and let gravity do most of the work. It’s pretty fast also.


  • It turns easily enough and emptying it takes a few minutes. The two-sided bins work well and hold a lot of refuse.
  • I just put a clean plastic kitty-litter type bin underneath, turn it so the opening is facing down, then carefully slide the “cooked” side open and gently rock the barrel to empty the contents into my plastic bin.
  • And as to emptying of a full unit just slide the slider over, it goes over or slides or comes out completely.

  • Best compost tumbler I have ever used I have owned three and this one is easy to use and empty.

  • Neighbors had this, and I bought it! Easy to use and easily emptied into a pail for putting in your garden!

A Tumbling Compost Bin With Dual Chambers!


The dual chambers should make for an easy way to let one side do it’s thing after full while still being able to add new material to the other side.


  • This dual-chamber tumbling composted is awesome. It’s very sturdy and feels solid in quality.
  • I like that it has two chambers, so you can feed one while the other is “cooking.”
  • We have one batch already in the tumbler. I did lots of reading and two chambers are highly recommended.
  • The compost tumbler is doing great! The first side has finished compost and the second side is “cooking”, and getting there.
  • Love the two chambers. Had kitchen scraps started in a bucket. Very easy system. Very pleased with this sturdy yet simple design! Highly recommend.
  • The two-chamber design is smart and once there’s enough material to start the composting process, it’s large enough so you’re not emptying it all the time.
  • I set it up with 2 chambers. One for the compost that’s been there for a little while and then once that gets full we use the other chamber.
  • What I love about this particular tumbler is its two-chamber design. I can fill one side while the other is curating. 
  • Having 2 chambers is great as I will fill one over the course of a summer, then let it finish the second summer while I fill up the other chamber.
  • This system allows you to make your composted ingredients THEN LEAVE IT ALONE AND SPIN IT while you create another mix in the second chamber.

A Black Tumbling Compost Bin That Is Critter-Proof!


The best thing about it is that it keeps out rodents & other critters who always got into our big heap then our Dogs would bark at them in the night as they raided our heap.


  • This is exactly what I had in mind for a compost tumbler! It’s contained, closed-in to keep critters out of it, unlike the other one I had.

  • No problems with critters, though there are squirrels and skunks in the neighborhood.
  • So far it has done a really good job of keeping in any sort of smell so I don’t have annoyed neighbors, is obviously very critter-proof (minus all the tiny bugs and ants that get in), and everything is decomposing nicely.
  • This rolling composter is easy to rotate and off the ground, therefore no little critters have access to rotting materials.
  • Also great customer service. I don’t usually write reviews, but they deserve some kudos. They’re responsive and they stand by their product

Great Compost For Your Garden!


I had two wheelbarrow loads of compost, which I put in my vegetable garden before planting tomatoes, beans, and okra. The garden is doing great, producing a lot of beans, okra, and beautiful, juicy, meaty tomatoes.

  • Now that I have the composting tumbler it’s much easier to add compost and remove the good dirt to use in my garden
  • I keep a tub under and spray water into it to make a compost tea to water some plants.
  • This bin is amazing. It decomposes our food scraps very quickly. Our garden looks amazing.
  • You can just as easily make compost tea by using a handful of the compost and letting it sit in water for a while.
  • I’ll soon use the finished compost to side-dress my okra in the vegetable garden.
  • The Compost tea drips from these holes so put a bucket under and voila!, instant fertilizer.
