I've been using our bins for about 8 months now - we put the contents into the compost bin after fermentation.
I have to say they are very god, but they REALLY stink - my hubby almosts vomits when he has to empty it! We're not as good at daining off the juice as we should be (because of the smell) so i know thats not helping
The food is always still recognisable after fermentation - particularly at the top of the bin, you'll find that at the bottom of the bin its a light brown mush.
