Works great. Assembly was somewhat challenging
Works great. Assembly was somewhat challenging, but not too much so (make sure to watch video on YouTube first). Composts very well, minimal leaking, takes about 4-5 weeks for a chamber to ripen fully. Terrific solution for kitchen waste. We bought two, so in winter, when composting will slow down, we will not run out of space. Built well, solid and sturdy. Very, very happy with the purchase. Update after almost three years of use: Well, these composters are one of the best thing we ever bought. We live in climate zone 5a, so winters are somewhat harsh and rather snowy. Our composters work year round without fail. All kitchen scraps, food leftovers, some (but far from all) garden waste, paper towels and napkins are now turned into prime quality compost. There is minimal leakage from the bottom of the barrels, but since they are located outdoors, it is not an issue. In winter we can see steam rising from the venting holes, that is how hot it gets inside the chambers. I have been playing with different proportions of the brown/green waste. Sometimes I add peat moss, sometimes alfalfa (buy it in the farm store, where they sell it as food for rabbits), sometimes just shredded paper (checks, documents etc) from our shredder, sometimes shredded leaves. It always, always works. A couple of times felt that it would be beneficial to use compost accelerator. Just so the chambers get somewhat of a "do over". Used it, again results were great. We are now never without compost. With four separate chambers in different stages of ripening I always have some compost ready to add into the planting hole or just spread around. The paint on the composters faded a little bit in the sun, but they still look pristine. Rain washes them, wind dries them off, no other maintenance is required. Also worth mentioning. I have two old metal wheelbarrows (got one at a yard sale for $1 and another came with the house). They are beaten up, but I will never get rid of them, since they fit perfectly underneath the composters for emptying. These wheelbarrows have low profile and are entirely made out of metal. I just roll one of them underneath the chamber to be emptied (right to the cross on the back), open the chamber door and rotate the composter. Works like a charm. It sounds ridiculous, but these composters now are one of my most prized possessions.... Yeah, I know, gardeners are nuts..... Update after 7 years of use: Still using this composters and still loving them! Came to check if these were still available beacause I just recommended them to someone. Was astounded to see a negative review (with photos). I do not know who these people are, I do not know what their deal is, but their composters had to be fully submerged in acid to look like they do. Here are pictures of our composters, located outside (no protection) in zone 5, after seven years of use. I rely heavily on reviews when purchasing new items, hopefully this will help.

Not an easy screw.
Well, I finally got a compost tumbler. After much research (I originally wanted a mantis) I found that most people using a tumbler preferred the Joraform. It looks nice, is sturdy, well made. Why not? I don’t spend large amounts of money on myself, so I asked for it for Mother’s day. My husband finally ordered it around June. (Late, I know.) It arrived the last day of August. So shipping through Amazon was unexpectedly long. No biggie. I have a lot to learn about composting and wasn’t expecting to get it going in any real significant way this year. It wasn’t until mid September that I had a spare day to assemble it. Since my hubby had a project going outside, I thought we could spend the day doing our projects together, 6 feet apart. (Sounds Covid-y.) He started installing his cold air intake and I started on the Joraform. I actually did as he did and pulled up the assembly video (made by Joraform) on youtube and watched the whole thing first. Then I rewound it and started with each individual step. It was surprisingly easy. I even stopped to help hubby with a fee issues he was having with his project. It finally came time to put the panels on. It all went to hell from here. Now, to be fair, the assembly video said you “may” need a second person to do this. It should have said “You will need a second hand and a 250lb gorilla to accomplish the next several steps.” I managed to place the first panel on my own. It was tough, but I got it and my false sense of accomplishment set in. Then, panel number two. Holy crap. There was no way that thing was going on. The foam inside, while snug, was so tight fitting that there was no way I could line up the holes. I struggled. I got mad. So I stopped and helped hubby finish the cold air intake in exchange for help with the Joraform. We attacked together. Even my husband, with his sexy arms of steel, were no match to push down on the panels to align the holes for the screws. We maneuvered and turned and swapped places with no avail. There was no way of getting enough pressure onto the thing to align it all. I finally suggested we should lay the thing in it’s side and have him and his 200lb self sit on the panels. It mostly worked. I still had to exude large amounts of force to get the screws to go into place. I did not realize, but at one point I was grunting to get the screws in. I glanced at my hubby and he had that silly grin and was raising his eyebrows at me. He mentioned liking the noises I was making. I very quickly made sure there was no more grunting of any kind, but that didn’t stop him from copping a feel every moment he got a chance. I finally told him to finish the screws. (Another cheeky grin from him.) But alas, my weight was no where near enough to press the panels down to align the holes. Fatty had to go back to sitting while I did all the work. We finished a couple hours after I started on it. I think it’s going to be a great tumbler, but don’t order it unless you have a gorilla or a horny hubby to help you assemble the darn thing. Don’t trust the assembly video. It is NOT an easy process. On the upside, he got his cold air intake installed and I got my tumbler assembled and we both got a workout in more than one way!! 😉

I love my Jora Composter. It took a little work to assemble. Review online Youtube videos before to orientate. It robust, and rotating and aerating is a breeze. No smell. I enjoy it a lot.

We've just started using our composter. It seems to be great - I have high hopes of great easy compost for the garden. It took two grown men over 3 hours to assemble - it's fiddly and the assembly instructions aren't IKEA standard. The instructions on how to use were in Swedish (not super helpful for non-Scandis). However, I found the instructions on-line and downloaded.

Had high hopes of this product, it arrived well packaged and I and a couple of friends set about assembling it. Very disappointed to encounter problems with panels that didn't go together as expected, the insulation seemed to be proud on a number of panels and only through brute strength did we manage to get the self tapping fixings in place. Noticed that there was daylight between most of the panel joints and wasn't overly surprised when water ingress through these ill fitting panels made the proposed compost very wet. Used a silicone sealer on the ill fitting joints and things are better but I will wait and see how things develop. Perhaps I just got a 'Friday afternoon' unit or maybe it's a very good idea poorly executed ( and I speak as someone who built up an engineering manufacturing company from scratch such that I was able to sell it for many millions and retire at 56 I.e. I am not a mug punter when it comes to manufacturing and engineering) Overall I would think that caution should be exercised if you buy a Joraform, at the first sign of ill fitting parts, package it up and send it back, I should have !
