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 bought my Mantis compost tumbler about 15 - 20 years ago. It's been well worth the expense. It's time for me to replace it because there are rust holes, but it's held up beautifully for so many years. It's easy to turn and I love that it is enclosed and rodent-proof! I think I can rig something to extend the life of my compost tumbler (like lining the inside with hardware cloth) and I will do that, but I'll also buy a new one soon and maybe just put fall leaves in the old one.

Comments about Mantis Compact ComposTumbler:
Just got my first original compost unit and have assembled and loaded it for the first time. As it is the first of March in North Carolina we have good and not so good days weather wise. My neighbor has two of these compost tumblers and now that I have retired I have expanded my garden. I am very excited to have my own tumbler. I did use some of the starter with the first load to counteract the weather. Very satisfied so far.

Comments about Mantis Compact ComposTumbler:
The gear sprocket that turns the drum was not in the box. I called and left a message for customer service but nobody followed up on it. I eventually just put the unit together without the sprocket and now have to turn it by hand, which is sometimes difficult.
