Product review (4 stars): Good value
Works good but fits so snug, it is hard to get refuse to go between flaps into disposal without using a utensil of some sort.  Other than that, it fits fine into my sink and helps block off some of the disposal noise as well.  This is the model you want if you find the ones available at your local big box store are a little too big.  (I made that mistake before ordering this one on line.)
