There is actually quite a lot of difference between Subpod and the Tumbleweed in-ground system.
The main differences are:
Subpod composts 15kg/30 litres per week.
Wormfeast (Tumbleweed) composts 1-2kg per week.
Subpod has an aeration panel - which means an aerobic system - not smelly. https://growhub.subpod.com/posts/does-a-subpod-smell-doesnt-all-compost-stink-how-does-the-subpod-manage-to-avoid-rotting-smells-since-it-is-a-composter
Subpod has a built-in seat so you can put them in schools, community gardens, or just use it in your own garden to have a rest amongst your veggies :)
Subpod has a worm tea outlet if you would like to drain the worm tea to use around other parts of your garden. https://growhub.subpod.com/posts/how-is-the-subpod-plumbed-to-collect-worm-teajuice-how-do-we-get-the-worm-tea-from-the-subpod
Subpod has a divider so that you can compost things such as onions. https://growhub.subpod.com/posts/ive-heard-you-shouldnt-compost-onion-and-garlic-what-about-if-its-cooked-into-a-meal-or-the-skins
Subpod is made from PP and will last 10-15 years https://growhub.subpod.com/posts/what-is-the-subpod-made-out-of
Subpod is a modular system so can be used for large scale composting.
