I did a lot of research before ordering a compost bin. The video is very self explanatory. This is the easiest compost bin I have ever put together. Put it together in 15 minutes, not like the others with all of the screws, that dont line up or dont stay in place or fit. This composter is very sturdy. very well made, designed, and has very think plastic tumblers that will not fall apart. It also has fins or paddles inside to stir, separate, and aerate your compost. It also has nice size doors to add or take out or empty your compost materials. Also has good size holes for air flow. All you need is a small mallet because the pieces just snap together and a Philips screw driver to put the legs on. It also has stoppers so the bins will not roll if you dont want them to. Very impressed and well worth the cost. I would buy again in a heartbeat. Shipping was fast. Dont know how it compost yet, since I just got it, but I have no doubt that it will be perfect.
