Got this when raccoons found the scraps in our enclosure. Bought this composter last spring and no animal problems since. I like the double tumbler too - at the end of last season, moved to the new bin and let the other stuff bake through fall and winter. Great dirt for this years garden and no separating dirt from new scraps.
I don't add dairy or meat. I compost a combo of fruit and veg scraps, coffee grounds, grass and leaves. I do compost eggshells but (1) they do take longer to break down and (2) you need to make sure your compost gets hot enough to kill any germs. Our compost actually steams in the summer (we compost the grass and leaves next to the tumbler and then add some to each side of the tumbler to mix with the scraps to help it along) so I think it gets hot enough. If you are not sure or are more cautious, you can wash them in warm water before you put them out.
OP here. Thanks! This looks like the right thing for us. We eat a lot of produce, and make a ton of coffee, so it should work fine.
