Product review (4 stars): Great bag for the price.
I inherited a trash compactor when we purchased our house.  I tried the paper liners but was not thrilled.  I then changed over to the plastic compactor bags from Sears.  These were expensive but fit well.  I saw these on Amazon and tried them since there were much cheaper.  The fit is decent although if you want to attach the bag using the "knobs", it can be a little tricky.
