This is an awesome burger press. It is made of sturdy steel grade and has impressions on the inside for 'lines' in your burger. I have had other plastic burger presses. This press will allow you to have a nice thick burger and doesn't stick to the plates. Now my husband is the griller in our home and watches many a food network grilling cookoff shows. He was thrilled when this arrived so that he could make a 'juicy Lucy'. It worked just fine for him to have items in the middle of the burger.
