Poor weld or glue job of lid to base.I believe that after a few washes it will become bent or flexible and the patty size mechanism will be tough to turn.Avoid.Pick another model. -- June 2010 update... For what it is worth, I returned this item in 2006 and bought a Tupperware Hamburger Press (without all the Tuppperware add on's) and it works as good as the day I bought it.Click Here to see more reviews about: Stainless Steel Hamburger Press
