I am a new mom and I didn't think I needed a diaper pail because I thought a trash can would do me fine, but now I am glad that I received this at my baby shower. It has a canister that you fill with baking soda and attach to the top of the lid. Every time you close the lid it disperses baking soda into the bag and then the bag is sealed. It really cuts down the odors. i did not give this 5 stars because you really need their bags in order for this to work effectively which means more money out of your pocket. Other than that this product is something I have recommended to my friends that are new mom.
