Product review (4 stars): Odor disc
I bought this item when my trash compactor was new and don't think I will be getting another one.  I really don't throw away food (or food "parts")  in my compactor as I bring those outside to my garbage can.  Maybe if I did toss any food remnants in the compactor, this would be a good product to have.  But as it is, the disc emits an odor - probably to combat the odors in the compactor.  And, I am not a real fan of the odor the disc emits on its own.
