Review on Chef-Grade Corn Cob Kernel Stripper & Remover: Quick, Cleanup-Free Option to Easily Peel and Collect Kernels. Safe, Convenient, & Efficient Kitchen Tool for Soups, Salads, and More - BPA Free by Patricia Muller

Can't put zero. Does not expand to piston size. Even if the plunger fits in the container, you only fill one container and it has to be emptied each time, slowing down the process. In addition, the shell matrices do not separate or close easily. Tried it over a bowl without a tray but couldn't stretch it. If you look closely at the cutter you will see a bad design that shouldn't be extended even though the advert says it can. Don't waste money
