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:
I obtained mine from a neighbor (already assembled) many, many years ago, and this composter has held up very well over the long term. I replaced two air vents on door lid when bolts rusted, but now the drum itself has some holes rusting through. Is it possible to replace the drum alone, or do I need to buy (and assemble) the entire unit (with stand, etc.)?

Comments about Mantis Compact ComposTumbler:
This is the second composTumbler I've ordered from Mantis. It's been 12 years + of my using the first tumbler. The current tumbler still functions as a composter but the handle for rotating the tumbler is broken. I decided to purchase another Mantis tumbler because of it's age overall. Otherwise, I am pleased with the Mantis compost system.
