Not sure what my $50 got me.
While my husband doesn't think it controls the odor at all, I think it does...a little.Instead my complaints are in its design. It's small. The lid is a pain to operate. You definitely need two hands to operate, so don't bother picking up the baby until you are done disposing of the diaper. My babysitter constantly shuts it off because she thinks it's the button to open the lid.So, in short, it probably does keep the air a little less stinky, but the ergonomics of the product are poorer than poor.
