This was purchased to put in my new kitchen sink. It is a slightly convex disc with a silicone or rubber edge. I have found it fits better with the concave side uppermost; it fits the modern plughole well, straining out small particles of food, but letting the water flow out freely. Although it can easily be removed to clean, it is not dislodged when I empty the washing up bowl or turn the tap on full. The silicone seems to keep it in place. Although expensive, I am pleased with this purchase as it will hopefully stop my sink getting blocked.
