I keep a few of these under my kitchen sink because inevitably someone who visits us wants one. I crack up when they ask me where I got it...Hello?? I own a kitchen store..!!! But I can't fault them for loving this simple little tool. It makes life so much easier by letting all the water run out of the sink but not allowing food particles and forks to go down the drain. It's made of stainless steel so I toss it in the dishwasher when it gets a little cruddy looking. It measures 4 3/8" across the top and is made to fit a standard 3 1/4" sink drain.
