Bests & Worsts Reviews from Amazon

I ordered these in March 2019 for my composting toilet. We dispose our humanure into a compost pile a bit away from our house. Before I added these bags of humanure to our compost, my compost would break down and get smaller over time. After I added these it would break down slower; not only has it filled the compost up faster without shrinking as it usually does, but the plastic hasn't broken down at all. I see no signs of degradation. I don't know what the time frame for decomposition is but these aren't composing in my compost pile. I read that it can take 3-6 months to compost a compostable bag -- the bags haven't composted and it's been almost 9 months. Now I am worried I will have to sift through my entire 'humanure' compost pile and hand remove all the bags. Disappointed and won't buy again. Totally bummed. I did an internet search and can't see anyone anywhere who has actually tested this product to see if the plastic is still there 3-6-or even 12 months after actually burying or hiding their poop, and that's without a composting pile.
