Rated 4.3 out of 5 by 346 reviewers.
Rated 5.0 out of 5.0 by Very Pleased The tumbling action is very smooth, even when heavy on one side. I like the two divided sides - it allows you to fill one, and then switch to the other. It really is easier if you have two people to do the assembly - be prepared for a lot of nuts and bolts. The product is definitely living up to its claims - would purchase it again in a heart beat June 20, 2014
Rated 5.0 out of 5.0 by Great Little Unit I bought this for my apartment garden, limited space but wanted to do something with kitchen scraps other than toss in landfill. I had read reviews about it being difficult to assemble, but this is not an issue for me. It took about 30 minutes and the instructions were really simple to follow if you read them. Currently have the first compartment being filled, will see how good the process works once I start the second side. November 27, 2011
Rated 1.0 out of 5.0 by Does not compost easily as led to believe. I have been composting for a few years now and have always wondered if a tumbler would be better for composting...boy was I wrong! Previously I had a traditional compost unit sitting on the ground near my shed and it continuously put out good compost and was almost always "hot" and cooking. The problem was, despite my efforts to only put in veggie material, coffee grounds, shredded paper, etc pests were still attracted to the bin. This Spring I decided to get rid of this bin and buy the tumbler above. Assembly and setup was easy and I would give it 5 stars on that front. I added my first batch of material in early mid to late April the first compartment was full and I began adding materials to the second compartment. Around early May I noticed the "curing" side was becoming a "slimy sludge" that smelled really bad. I couldn't understand it...this was the same material that when added to my ground bin heated up and broke down in a matter of weeks (remember I have been doing this for quite some time and know very well about ratios, etc). I did some reading and found information indicating that composting in a tumbler is quite different than ground composting because it is in fact the bacteria from the ground the powers the process of composting. So I decided to add some dirt directly from the ground, a batch of compost accelerator from WalMart along with a good load of sawdust to try and dry it out a bit. This did not work either and the batch remained just a big wet ball of sludge. Thinking that maybe it was the excess rain we were having in the Spring that might have caused this (maybe the ventilation holes allowed too much rain in?) I decided to wrap the bin in a tarp so that I could control the moisture in the tumbler. I emptied out the current contents and started over...same result...a putrid mess of slime and sludge. I decided to try an experiment to rule out that it could be the materials I was adding. I mulched some leaves along with bark, sawdust, coffee grounds, egg cartons until I had it just the perfect ratios. I put one batch in the tumbler and one batch in a trash container with the bottom cut out. The batch in the trash can composted after a very short time...the batch in the tumbler, once again, was a gross mess of slime and wet "goop". After more reading I found that you need to be something akin to a scientist to get everything just right to compost in a tumbler. Needless to say, it was a big disappointment. I returned to my bin on the ground but this time I buried the bin about 3.5 feet down to eliminate the problems with rodents and pests getting in there...and after only a short period of time I have a good batch "cooking" again using the same materials I added to the tumbler...I'll probably just use the tumbler to store a cured batch in.

Rated 5.0 out of 5.0 by Great Composter for the Small Home Garden I purchased a tumbler because I got tired of attracting opossums, raccoons, herbivore dinosaurs, etc by doing the lazy mans way of composting....Dig a hole in the garden throw the kitchen scraps in and let nature do what it's designed to do! I mean the stuffs going in the garden anyway right? But this doesn't work well for larger volumes of yard waste like grass clippings and such. (The critters above also seemed to enjoy the desserts I left and didn't mind digging for them too.) This tumbler solved those problems and also made it easier to add rich compost to my newly built raised beds. I'm also convinced tumbling, rather than pitchforking your pile, multiple bin piles, or other methods - is the way to go. Seems more efficient, easier, and suitable for the small-potatoes gardener like myself. Assembly of the unit was fairly easy and painless - just follow the directions, take your time, and think ahead. The directions aren't the best - but lay the pieces out and see how they fit together and you'll be good to go. It took me about an hour and a half to complete the process with only a few - reversals to get things right. I've had the tumbler nearly a year now - bought it last fall and it's held up well. Decomposition was a little slow at first but I think that's because the compost had a difficult time getting up to speed with the cool temps. The barrel leaks a little bit but that's probably a good thing rather than having a soppy mess in the tumbler itself when it receives too much moisture. ( I need to find a suitable tub to catch the leakage for lovely compost tea.) Speaking of which? It if does get too sloppy inside? Just remove the lid and let the summer sun and the microbes evaporate the surplus. That sure works well in our Oklahoma heat! So also think about location too. Putting the thing under a shade tree might seem like a good idea, but then you're expecting biology alone instead of complete physics to work in conjunction with the barrel - especially since it's black and absorbs a ton of sun to help with decomposition. Also don't forget this IS a tumbler so the more you tumble? The faster stuff gets mixed up, aerated and breaks down. Tumbling when the compost gets sort of "settled" into a clump is a little tough, but add some more fluffy, loose stuff - tumble again - and you'll have a better mix and easier tumble. The two chamber system works ok - but I've rarely used it simply because the chambers are relatively small. A necessary engineering design of course because if you get the thing too big then you won't be able to tumble it well. In the summer decomposition is happening so fast anyway that I just fill both chambers up and tumble frequently. Within a matter of days what used to be at the top is now reduced by at least half. When things look pretty well broken down - and not four-legged critter friendly - I throw the stuff in the garden where it's needed. The two air vents on the side seem like a design afterthought. They don't stay in the full open position too easily (especially after a good tumble - they are rather loosey-goosey) and if your tumbler is anywhere near 2/3 full I'm not sure how much air is circulating to the pile through them anyway since the holes are covered by the compost. Oh well. I guess enough air is getting in through other means because in my tumbler things appear to be breaking down quite well. I just shoveled compost out when one chamber looked ripe. I overlook the obvious and now it seems that probably the easier route would have been to rotate the barrel with one chamber open and just dump it out! I know that there's all sorts of fancy advice and such to figure out what to put in the tumbler and how much - but again, I'm a lazy gardener and figure if nature has been making compost for millions of years without our help - it will continue to do so with minimal assistance from us now. Variety is the spice of life and so it seems it is with compost. I noticed better results when I threw in grass clippings, leaf litter, fruit and veggie scraps, compostable peanuts, sunflower stalks - the more variety the better. I add avocado pits and other roundish things too. In my head I'm thinking maybe these bang around the tumbler and help move things around and break up stuff too. Easily removed from the final compost if they haven't broken down already. Citrus peels add a nice aroma to the pile, break down fairly quickly and the decomposers don't seem to mind either. I also add a bit of old potting soil and garden dirt too. Figure there's good little buggers in there too. If the number of bugs I have crawling around eating the stuff that's in the bin is any indication - LOTS of decomposing is going on and therefore great compost thanks to this tumbler! August 4, 2015
Rated 3.0 out of 5.0 by Leaks but nice size Took a while to put together because there are a lot of nuts and bolts that are hard to reach at the same time unless you have long arms. It leaks smelly liquid from the seams and when you turn it the smelly liquid leaks all over. I wanted a composter that I could have on my deck and I love the size but the leaking will end up making me move it to the garden. I have another composter that is not suitable for the deck that does not leak like this. July 1, 2014
Rated 4.0 out of 5.0 by Not bad for the size and price Good little composter. Perfect for beginners. Easy set up. Not sure how long it will last, but after a few months, still going strong. May 21, 2015
Rated 5.0 out of 5.0 by Works, cheap, good product It's not big, but it's big enough to put all your table scraps and maybe two bags of lawn clippings (one on each side). Give it a couple of days and you'll be able to fit more. It's easy to put together. It may seem that the axle it spins on is too short, but once completely together, it's fine. The doors are a little small, so you'll end up spilling grass clippings everywhere, but you shouldn't expect it to be clean due to drippings. Otherwise, good product. July 23, 2013
Rated 5.0 out of 5.0 by I love my new composter with 2 chambers! Although it felt like an IQ test for assembly, once I got the concept it was easy! I keep a little composter container on my kitchen counter, I use a bio bag and then place it every 2 days in my composter. Turning it is really easy and there is no odor at all! April 23, 2013
