I received our Vitamix Foodcycler on Sunday and am stoked about it!  My first batch of soil was a disaster.. I had some rotting apples so I threw them in there.. that was a BAD idea.. they hardened and froze the machine up and getting them out was a task!  But I have made two batches since (not containing any apples at all this time!) and things have been going swimmingly.  The soil really does smell 'nice' and it is super-quiet.  I do not regret this buy at all!
