Quality!
"It is so well made. When you hold it in your hand, you can feel that it's solidly made and not prone to warping over time. It does stick very well to smooth surfaces and my baby cannot rip it off like the ezpz plate. Of note, however, Stokke changed the surface of their tray table for Trip Trapp and the plate unfortunately does not stick. We put the chair underneath our quartz dining table and stick the plate on the table, which works well."
