  • Good quality product!
Color: Black
This thing works great! Takes up a little space but so does a compost pile or bin. It holds a lot of food waste which turns into to really good compost! I do personally add some blood meal every once in a while to help speed up the process. I will say it was a little bit of a hassle putting it together. If I remember correctly it was the center divider between the two compartments that was the hardest part in the assembly. I will also say it does get extremely heavy when trying to rotate it after it gets pretty full. I do also recommend breaking up your eggshells bed throwing them in. ... show more

  • Pretty decent but center divider *** DOES NOT FIT *** repeat *** DOES NOT FIT ***
Color: Black
First, the pros: 1) Extra screws and nuts were provided. This is rare nowadays, but this came with 4 extra sets of screws and nuts and 2 extra center pipe end caps 2) The nuts are self-tightening: you only have to get them started a few turns then you can screw the screws from the outside (with the included Philips screwdriver) and they will tighten without having to hold the nut with your finger or a wrench. This is key since it is hard at times to wrap your arm inside of the bin to hold the nut while tightening the screw from the outside. 3) Thickness of the plastic is pretty good for what this is. It presents as fairly sturdy when assembled. 4) Large size. I got the 43 gallon model and I can tell it will hold a lot of compost. 5) The tumbler rotates smoothly and easily. 6) The legs are sturdy and easy to assemble. Now the cons: 1) not that easy to assemble. I'm 60 years old. I've been around the Ikea block several times. I've assembled huge pergolas and gazebos and carts and sheds and all varieties of machines and devices. I have every tool. I can do plumbing and electrical work, carpentry, both rough and finish, drywall, irrigation, tile and marble. I've done it all. But this wasn't that easy to assemble. The worst part was thinking the center divider should fit nicely into the center grooved channel that goes around the inside perimeter of the tumbler, when it doesn't even come close. I think the manufacturer said, "let's use one center divider for all the different tumblers we make, fit be darned." I spent more time trying to make the center divider panel fit than assembling the rest of the unit. Check out my pictures to see how poorly it fits. I tried flipping it over, rotating the divider every which way, but nope, didn't happen. 2) You have to work your way around the tumbler, adding one panel at a time. It was difficult at times to hold the panels in place while I was screwing them together. There are these raised, stubby posts that are supposed to snap into holes on the adjacent panels and many times the snap was not as snappy as it should have been. Some of the connections seemed a little loose but upon completion, the sides seem to have pulled together as a team and the weight of the compost may push the edges out enough so that those posts snug up against the holes. Summary: I believe this was worth the price and it will function well for several years. ... show more

  • Well made, very sturdy

Love it! Easy to put together and very sturdy. Doors could be a little bigger, but otherwise, can’t wait to try it.

Instructions for this thing sucks but it works well and is affordable. Didn’t take long at all to build once I found a YouTube video lol.

  • Not easy to assemble.
Color: Black
Assembling this product was not easy and I'm no stranger to putting things together. The holes were mismatched and I ended up need to drill new ones, the screws were too short for several panels and I had to buy longer ones. Also the doors are very difficult to slide open and closed. I'm sure the functionality of the product is good, but the assemblage is not. ... show more

  • Easy to assemble, does what its supposed to do. Patience is key.
Color: Black
Easy to set up and easy to use. Doesn't take up much space at all, especially around your garden. The composter has two separate sides for two different batches of compost. There is a sliding door on either side that makes it easy to check on the progress of your compost easily. We start one side and leave the other side empty for a while so that were able to turn it and mix it up easier. It doesn't have a handle or anything but it has grooves to grip and turn it. The biggest sticking point about this item is BE PATIENT. This is just a compost bin, it doesn't magically make compost, that happens naturally. Fill it up, wet it down, keep it spinning, and you'll be composting in no time! ... show more

  • It’s Awesome (once it’s put together)
Color: Black
This composter is exactly what I’ve needed! It’s easy to turn, contains the smell, and is massive while also being compact! I took one star off because assembly is SUPER DIFFICULT. It took me over an hour and a half to get it put together and the instructions are terrible. The center divider seems useless and more in the way than anything, getting it in the brackets while installing the final pieces was extremely difficult. It has gaps as well, so it’s difficult to assemble. When empty, it’s very light and easy to move. Overall, I have about 5 gallons of compost already that I just had in a bucket on my porch in it, and there’s still so much room!! It’s easy to till and the doors slide open and close pretty easily (they do stick a little bit). But overall a great product and I’m excited to use it and grow my composting amount/process. ... show more

  • Excellent Compost Bin
Color: Black
It has been 4 years since setting up this product and even in direct UV light, it has not shown any signs of discoloration, distortion, or drying out but the steel pipe frame is showing signs of rusting out in some areas so be sure to either recoat the frame or you can touch it up in some spots as they happen. Great product nonetheless and at a great price. Assembly can be a bit weird and confusing but once you get two sides going, the rest is a piece of cake but follow the directions as there is only one way to assemble this product. I would definitely recommend this product. ... show more
