the best bin i have is a Gedeye bin. it’s definitely not fancy but has consistently worked better for me than other bins i’ve had. i turn the compost over regularly but, that’s because i have fair amounts of matter to compost, and i don’t want to wait 6 months for finished compost. Here are the features of the Gedeye i found useful:
- not too expensive (approx $90 for the big model)
- one piece + lid, so it’s sturdy. you can lift it off and leave a “cake” of compost, to either turn into the empty relocated bin or to use. modular bins are very difficult to lift off to turn the compost, so you have to shovel out half these bins through the top, before you can lift off. those slide off panels are an absolute joke and no use whatsoever, when it comes to practical composting.
- keeps the matter moist all the time, and does have some airflow into it via lid handles. the modular bins always dry where the slots are.
i haven’t used hi-tech bins, as i wouldn’t spend that much money on one….most of them cost as much as several tons of ready compost from compost suppliers.
