I purchased the FC-50 about a month ago and love it!  
We use it quite often (although it's just two of us)  - we put our vegetable scraps & ground coffee in it daily.  We let it run overnight, so it doesn't impact our day to day activities.  (we live in an apartment - so not much space)  

The amount of garbage we accumulate now is so little, I'm so grateful.  Much less trips to the trash can outside.
