I've been using the liners and they are ok but the design makes the grease run back in and under the liner at the drain tube. the rolled edge at the drain tube hinders the flow of the grease, why not extend the foil into the drain tube for easy flow to drain. What is the purpose of the tab anyway? I thought it was to go on the drain end until I read the instructions on the package. May switch to foil after I use up the rest of my liners. Thanks
