Summary: easy to use and works as promised from Tigard, OR– Snaps on and off with ease. I really wanted the translucent tray but it was double the price..who really cares about the color. Easily washes up and can be placed in dishwasher. Have not noticed that it scratches easily. Stokkes offers a 7 yr warranty. Have to either email card for warranty or register online...be sure to do such.
