I'm very happy with my Compost-Twin. The Compost-Twin took my gardening to new heights. I've always been dedicated to soil improvement. The Compost-Twin has greatly improved all the products (vegetables, flowers, mainly hot/exotic peppers) that I grow and sell. The output is tremendous. I'm definitely recommending this product to all my fellow home gardeners and growers. Thank you Mantis for this incredible machine."

I wanted to tell you how much I like your product; it is great. I grow palm trees as a hobby and I have been a composter for many years; after many year of arduous work composting with many backbreaking methods, I saw the superiority of rotary composters like the ones you sell. After looking at many brands of "rotary-type" composters, I decided that your ComposT-Twin product looked like the best one to go with. There was another brand that also caught my eye; however, I bought your product. It has served me well; you make a great product."

Mantis ComposT-Twin dual-chamber composter
The Mantis ComposT-Twin dual-chamber composter holds almost 25 cubic feet of raw material – that's 10 bushels in each chamber! Unlike traditional single-bin composters, the Mantis composter allows your compost to "cook" in one composting bin while leaving room for you to fill the second composting bin with more kitchen and yard scraps. Aerator vents on each door allow oxygen into the chamber while vented end caps assure even air flow and proper drainage. Bin contents are fully enclosed and latched to keep out rodents, pets, and other wildlife. No more messy, unsightly compost piles, no odors wafting over to your neighbor's porch. It's easy to remove your finished compost. The ComposT-Twin frame is a convenient 32" high for easy loading and unloading. The easy-crank handle and gear mechanisms make the drum easy to turn – even when fully loaded!
