So far so good. This is the first time I have ever put fruit directly in the drawer without the bag from the grocery store. The liner is like a thin see through breathable foam. It appears that as you put the fruit on the foam it lifts the fruit from sitting directly on the drawer bottom therefore allowing air to circulate beneath it. I imagine that this is what prevents the rotting. My fruit still looks good after 3 days. But lets be honest I buy fruit with good intentions and then never eat it and eventually it will go rotten. There is no magic foam liner for that. HA!
