The Lifetime 80-Gallon Rotating model is the big enchilada of self-contained rotatable compost bins, and it easily takes the cake as our favorite model. This compost bin has one large chamber with a support bar running through the middle, which has holes for additional aeration. It rotates easily and has multiple grip points to assist with turning. This tumbler is the only model we tested with an easy-to-use locking pin to prevent it from rotating. Our favorite feature is the huge door that you can open from the top and easily shovel in leaves or whatever material you're using to balance your carbon-to-nitrogen ratio, or to throw in some fresh food scraps. When it's time to reap the fruits of your labor &#40;actually, the microorganism's labor&#41;, you can open up the door and dump everything on the ground for distribution in your garden beds. Easy peasy.
This beast takes a while to assemble, and we strongly recommend having a power drill on hand for the many, many fasteners that hold everything together. While assembly is tedious, it isn't difficult. The instructions are very easy to follow, and the parts are well organized and clearly labeled. We believe the final product is well worth the time spent putting it together. This bin may be too large for apartment dwellers or other folks with limited space, but it's fully capable of producing high-quality compost while keeping the elements at bay and small critters out.
