I use my Compact Compostumbler only for compostable kitchen scraps, bolted or dying vegetable/herb plants, some leaves etc. -- I have a separate large compost pile for grass, weeds, and other yard waste. I could probably use one of the smaller composters that Mantis sells, but have had mine for over 10 years and it does the job. I have just ordered new panels for the drum, as the old ones have rusted through after a decade in the Pacific Northwest.
The cap for the handle broke within days of the unit's first assembly, but it didn't affect the composting function. Otherwise everything else has held up to normal wear & tear. It sits outdoors all winter and is still working, so that's quite a testimonial for this region.
It takes all summer to get compost out of the thing, but that may be due to the temperature and climate here, or to what I'm putting in it (or not). Honestly, it's most practical function is to dispose of kitchen waste in a manner that won't attract pests.

I have had this compact tumbler for about 5 years now. It is disintegrating with rust. The lid is cracking from the rust and bend of the metal and the opening is rusting and cracking. There is rust all the way around the barrel and the metal locks are rusted also. Now why on earth would you put metal that rusts as a compost bin? I live in Los angles where it barely rains and I do not soak my compost. Poor design and disappointed in my investment. It only comes with a 2 yr warranty I believe so that you have to buy the parts that a severely damaged. I was quoted about $85 to replace the lid and panel including shipping.

Comments about Mantis Compact ComposTumbler:
We use to make rich soil to amend the poor soil we have to contend with in our garden and flower beds. Much easier than traditional composting, now we will use our bins to store compost for the prep of each years growing season!
Our first batch was done in 12 days; we had existing compost from our old bins, wood chips, kitchen scraps and grass and weeds. Added water twice and bone meal.
Service and delivery comments:
Prompt delivery! A++
Bottom Line Yes, I would recommend this to a friend

Comments about Mantis Compact ComposTumbler:
Use it for garden clippings and kitchen scraps. Went this route because critters kept getting into my compost pile. Composts quickly and easily aerates the pile. One con is that it dents easily. My kids dented it and then the dent developed some rust and then it rusted through so I had to replace the lid.
Pros
- Just built the thing do not how it performs
Cons
- Very difficult to put together, a two person job
Best Uses
- I am using all of these items
Comments about Mantis Compact ComposTumbler:
Putting this product together was a total pain, need two people. It does look good on my lower patio and seems to be functioning well at this time. Filling it up will see how it performs over the next couple of weeks.
Service and delivery comments:

Comments about Mantis Compact ComposTumbler:
Initial stage decomposition. Once composted enough, will transfer to another bin for final stage.
Service and delivery comments:
Delivery was prompt. Unfortunately, I did not receive all of the bolts, nuts and washers required to assemble this unit (had to go to the hardware store). Great video on line! Much better than trying to follow the printed instructions!
