Sturdy just what the manufacturer said it would be, but not what it said this would do. Rather than composting my yard and kitchen waste, it seems to preserve it perfectly. Rain cannot get to the compost (or mummified remains, in my case) which I consider a con, as I must intentionally water it. Door at the bottom is small and, if I had compost, would make it difficult to get it out. I would say, if you are in the market for a composter, keep looking.
