I haven't used that one, or anything like it. For years I used a Compost Tumbler, and loved it. I did have to remember to turn it every day or two, but it heated reliably, never smelled, killed all weed seeds, was easy to turn, fill, and empty, and could make great compost in two weeks if I shredded everything pretty small. Unshredded stuff still works, but takes longer, and may require sifting, depending on your intended use.
For browns I use old leaves, old grass clippings from the lawn, shredded branches from pruning, sawdust and wood shavings from my shop or a nearby sawmill... Whatever I can find for free.
The only reason I no longer use the Compost Tumbler is that I got more into farming, got bigger, and got a tractor. I still shred most stuff, but now I just have a big pile, which I turn with the tractor bucket.
I stored finished stuff in plastic garbage cans, if I didn't have a use for it right away.
