These little inserts work wonders for the diaper genie. It basically absorbs any “toxic” smell coming from the Diaper Genie. I gave it one star less because the actual plastic holder is impossible to find to purchase again. It doesn’t stick very well on the inside lid of the Diaper Genie and we didn’t notice that it fell inside. So now these little refills are useless because there is no holder. Which is unfortunate because they do work.
