It works as intended and I like that the corners have a good solid rubber like fixed gasket, it allows for easy sliding without the worry of scratching your counter-top.  Ours is used in a  recessed sink application so slides on the Quartz.  In fact we liked it so much we bought as second, slightly bigger for our second stainless farmhouse sink.  If your looking for something with depth, however, don't bother as it does not hold much, there are plenty of other options out there.
