Perfect at home/backyard composter
I gave my dad this composter for Father's day. He's a versatile dude, liking both outdoorsy things and tech. He can be a hard to get gifts for each year, but I nailed it with this. The double barrel composter is large, but they had smaller options available. This size is what I knew would work well for the amount of food scraps/waste my parents produce and the size of their backyard/patio. It was easy to assemble, and once assembled, it is sturdy. It has been in use for over 6 months now and doing great. The doors slide and seem sturdy, but are also simple. It isn't reasonable to expect they would walk outside in the cold winter months just to drop an egg shell in, so I got them a small counter top sized container with an odor proof lid to dump their scraps in and take out once a week once full. It hasn't been a full year yet, but they are planning to use the compost as soil when spring comes again. They are currently using one barrel for scraps and have put the other 'out of commission' to let to product decompose into soil. My dad loves it. It is low maintenance, he only spins it once a day or so when in the backyard doing other projects. He's excited to use the soil in his plant beds this spring and feels good not throwing useful scraps in the trash.

Compost Delight
Assembling was some what easy for the most part but I had to improvise to secure “nut” inside the black cylinder stuffing it with plastic wrap then placed a piece of duck tape at the end of round black cylinder to prevent the bolt “nut” from falling out of its compartment as I insert the screw to secure the screw & bolt “nut” to connect center bar so the compost can spin properly. No worries I completed it in a reasonable time. Stability is excellent. I will utilize on my balcony and so far I see no insects hanging around. Certainly do not want to attract rodents from unbearable odors. Seems to be great value for the money as far as the portability and the quality of materials of main compartment. Easy to rinse down as needed from what I can see. I added a little soil and compost accelerate to kick start the process. I’m new to this lifestyle and I am excited to be an active part of a community of this kind.

Good compost container
Ordered this as it seemed to be a pretty good size. It's smaller than I wanted BUT, the 2 separate containers actually will make it more productive compost process. I like that each side can lock into place. I am not sure the door is really strong but we'll see how it does over the winter. The directions were on my phone via a code. It was helpful for me, but I can see some people wanting a hard copy (you do have an option to print). Assembly was smooth and the 2nd barrel went much faster than the 1st. I thought everything was well labeled and straight-forward. After my last one broke, I did not want to spend a lot of $. I think for the value this should last a few years and that works for me!

99% easy.
The video instructions were right on. I am 77 and was able to put the dual chamber compost tumbler together. The only part I had a little trouble with was when I snapped in the top of the compost tumbler to the sides. 4 sides snapped in with no problem but snapping in the 5th part was no so easy. I did finally figure it out and the rest was easy from then on. I did take me about 3 hours....but well worth it.

3/5 for the tricky assembly instructions
I had one of those worm-migration compost systems but the worms all died, left for greener pastures or were eaten by the neighborhood skunk. So I needed a different system that could work regardless of worms. A tumbling one looked good so I ordered it. It seems much easier to dump your scraps into the door on the top and then later on, tumble the door to the bottom side and dispense the compost that way. The worm-migration setup was always kind of a mess. I haven't had time to check the composting abilities but the assembly was far from straightforward. For staters, the little black snapping things that you need to get the barrel put together are pretty flimsy. And I'm not exactly musclebound so if I can break them with little effort, they are far too weak. There are couple extras provided but they really need many more, since you can expect to break at least wo of them while you're figuring out exactly how much force you need to exert. Ditto for the screws. There should always be several extras, especially of anything small, because of course some will get lost in the chaos. The rest of the assembly was tricky too. It requires a lot of wriggling around of various plastic parts, and nothing really fits until everything does. One set of screws doesn't even fit its area properly but sticks out even after I've screwed it in all the way. How hard is it to send the correct size screw? The fact that there are no printed instructions and you have to access them online seems cheapskate. But they could have made up for it with a detailed video showing exactly how you manage the gymnastics to get the thing assembled. However once it was assembled, everything looked pretty nice and snugly fit. Just one of the green insert things keeps falling out because it doesn't fit right but that's a small issue. I just hope the earthworms are happy about how much trouble they've caused.

Perfect Size for Small Family
When I purchased this unit, I debated between this size and one of the smaller single units. I did not want an oversized bin sitting in my backyard. After using this mid-sized dual bin for 6 weeks, I can say it is the perfect size for our small family. We feed it kitchen scraps daily and both bins still have plenty of space for more. Being able to rotate the bins helps to keep the food scraps composting at a fast rate. We started the compost process with some brown material from our yard and then feed it food scraps daily. You can see and feel the compost process as there is a good amount of heat in the bins. We plan to use the compost in our raised bed garden after composting is complete. Assembly is straight forward and took about 1 hour. The quality and sturdiness is good and I expect to get many years out of it.

CAUTION: Challenging to assemble (I snapped the side connections!) - Updated 6/2021
[INITIAL 2020 REVIEW] As a heads up, the product does not come with paper assembly instructions, so you will need to go online to get them. While I like the idea of cutting down on paper, I always find omitting the instructions in particular to be a real nuisance and makes a product immediately less consumer-friendly. The main issue, however, is that getting the side walls of the product to properly snap together is a challenge. I couldn't seem to get things properly aligned and, when the directions online said to use a little force, the only thing I accomplished was buckling and snapping some of the side connections (note: I have minimal upper arm strength, and can say honestly that I was not exerting much actual force so this was surprising to me.) Because the product is now slightly broken, I'm going to need to find my own way to fit it together and mend any unintended gaps so that it can be (hopefully) functional. This is likely going to impact it's long-term stability and effectiveness, so I can't rate how the product actually works when assembled successfully. Overall, this was supposed to be my first foray into composting, so I'm a bit disappointed that I'm off to such a bad start. I think the product design could be tweaked a little to make assembly easier. It looks like it should be straightforward to put together, but even the slightest misalignment appears very difficult to correct and throws the whole thing off. If it had been able to assemble smoothly, I would otherwise have been very happy with the size and overall design of the product. [1 YEAR UPDATE - 2021] I refused to give up on this little composter. After a few weeks of huffing at the half-finished assembly every time I walked by it and occasionally attempting to wrangle all the connections together, I was finally able to fully assemble it. The side connection area I accidentally snapped in my initial assembly attempt didn't appear too noticeable in the end, either. Since assembling it, I have been using it for a full year and it's still holding steady. Yes, it was a headache and a half to put together - and I still think that's worth considering before you buy it - but in my case, it turned out to be worth it. I've found it's really easy to use and it does its job quite well. It doesn't take up a lot of space in the yard and is very discrete (it does fill up quick though! I find myself wishing I had bought the double composter option so I could start a second batch.) I would tentatively recommend this product for those who have the dexterity and patience for the initial assembly - or those who know someone else who can be tasked with assembling it for them! With this in mind, I've revised my rating from "1 star" to "4 stars." Happy composting!

Will likely work but poor quality control and questionable design
Update: I’ve used it for one season and obtained compost! This turned out to be a good size for a family of 2.5. Amazingly did not attract vermin despite the fact that I set it out next to our woods. As expected, it does leak “compost tea” so I would recommend against putting this anywhere other than flat ground. While it didn’t attract vermin, it did attract beneficial black soldier fly which are great for compost and largely stayed in the bins. We never noticed a smell, even when I accidentally forgot to tumble the contents for a while and it went anaerobic. Bumping my review up a star as a result of an overall successful season. Ordered this product and it came missing all of the connectors needed to assemble. The manufacturer wouldn’t replace so I had to initiate a return and replacement w/Amazon. When the replacement arrived it came with all the parts but a completely different set of gloves for some reason. Assembly was easy in theory but hard in reality because so many of the pieces have to be brute forced together. Sometimes they would snap in easily, and other times I’d get two pieces that seemed to be manufactured a bit poorly and it took a lot of effort to get them to work. And if you make a mistake at any point have fun trying to disassemble anything. Once assembled, it’s not as smooth or functional as I’d hoped. The locking pieces have already fallen off after less than one week of use. The “aeration holes” let things like coffee grounds, sawdust - and I’m assuming the compost itself - fall through, which means this isn’t suitable on a patio. Overall it’s fine. I think it will do the job. But for the price I’m not sure it’s worth it over the cheaper options.

Looks cute for a compost tumbler
It’s a basic tumbler with two chambers so you can start your compost at different times. To be honest, composting in the ground by burying the scraps works faster for me but I don’t have space in the garden to bury anything anymore. I don’t know how resistant the plastic to UV since I cover the whole thing all the time anyway. It also helps with keeping the compost warm. It comes in an unassuming flat box and the online instructions were easy to follow. I was able to put it together in less than half hour. The turning mechanism is smooth. Even at full capacity, it’s easy to turn the chambers to tumble the contains. The flaps aren’t easy to open so small children or animals wouldn’t be able to open them. I have no use for the lock mechanism that prevents the chambers from rolling but I tried it and it works. The holes in the chambers allow for air circulation but it also means that the compost juices will leak out. I put it on a patch of soil anyway so it’s not a problem for me but if you’ll do this on a patio or a balcony, put something under to catch the liquid. If you’re new to composting, just don’t forget to add some browns (cardboard, packing paper, dried grass or leaves) in there to prevent any smell.

Good for small family
Got a few reviews mentioning this is a bit small, but after using it for 1 month, I have not filled up half of one of the bin. So far, I am loving it. Ps. we are 2 person household, cooking daily.
